 On the **Concept** page *Add picture* takes a PNG, JPEG or WebP: move and zoom it inside the square window, *Use this* stores a small 256 px picture inside the character (so it is saved, shared, exported as JSON and loaded with it). The server checks and re-encodes it. The picture appears in the header of the character sheet (also when printing), as icon in the player bar of the lobby and as the token of the character on the map (in the player's colour ring). Only members of the lobby get the picture through `/api/lobbies/{id}/portrait/{username}`. The PDF / Word export from the server does not contain it yet.
 
+The portrait sits next to the name and identity fields on page 1 of the sheet. The two ruled note areas ("Conditions & notes" on page 1, "Notes" on page 2) can be typed into on the Summary page and, for your own character, in the lobby (saved automatically through `PUT /api/characters/{id}/notes`, which only touches those two fields). They are included in print, PDF and Word.

+Admins get an **Editor** tab to add, change and delete **items, item categories, skills, skill groups and professions** with forms. Admins are the usernames in `AW_ADMINS` (comma separated, set in `.env`); without that setting only the first account ever created is admin. Admins can also promote other users: the **Users and admins** card above the tabs lists all accounts with *Make admin* / *Remove admin*. Names in `AW_ADMINS` stay admin and can only be changed in `.env`; the last admin cannot be removed.
 
 - Changes are saved in `db/rules_overrides.json` (next to the database, so it is part of your backup). For each edited list it **replaces** the list from `rules.json`; the shipped file is not touched. A previous copy is kept as `rules_overrides.json.bak`. "Reset to shipped" removes the override of one list.
 - New entries get their id from the name (lowercase, `_`). Ids of existing entries cannot be changed, because characters refer to them.

+### NPCs, enemies and creatures
+
+The **NPCs** tab is a library of rules-based NPCs. It uses the same wizard as the character creator (attributes, skills, talents, mutations, equipment, portrait), with a free "NPC / creature" preset that has large pools and no profession requirement, plus a type (NPC, enemy, monster, creature, animal, robot), a default token size, a description, special abilities and attacks, and loot.
+
+- NPCs are stored like characters (flag `npc`) and are listed separately; they can be duplicated and shared with other DMs (read-only).
+- In the map editor and at the table, **+ From NPC library** / **+ NPC** places a token that takes the NPC's name, size and portrait. Plain **+ Token** still works.
+- The DM clicks an NPC token to see its sheet in the left column and can click attributes and skills to roll checks for it (shown in the chat as "NPC: Skill"). Players never see the NPC link or sheet.
+
+Players and the DM show a green dot in the lobby while they have it open (online presence over the WebSocket; without WebSockets everyone appears offline).
+
+### Initiative and fights
+
+The DM presses **⚔ Start fight** in the lobby. Every player with a character joins automatically and rolls initiative (1d20 + the character's Initiative value, as in the rules). **Right click** a token (DM, full view) for a radial menu: add it to the fight, open its sheet, hide/reveal or remove an NPC token. Players who join later can be added with the **+ name** buttons in the initiative bar.
+
+The bar shows the order, the round and whose turn it is (the token pulses on the map). The DM can overwrite every number, reroll, remove entries, step **◀ / Next turn ▶** and **End fight**. Hidden NPCs are not shown to players. Fight start, joins and the end are logged in the chat feed.
+
+The top of the lobby is one compact row: small buttons on the left (start fight, previous/next turn, end fight, ▾ to expand players and difficulty), the player bar – replaced by a scrollable initiative bar during a fight – and the lobby settings button. Players only see the name of whoever's turn it is; NPC names are not sent to players otherwise, and token names show on hover, selection or turn. The sheet and the chat can be resized by dragging the thin lines next to them (remembered per browser).
+
+### HP, conditions and fog of war
+
+- **HP and conditions:** select a token (DM, full view) to edit its HP (−5/−1/+1/+5, max) and conditions from the rules (click raises the level 1 → 3 → off). NPC tokens from the library start with the NPC's Health value. Right click the token and use the **HP** and **Cond.** toggles of the radial menu to decide when players may see them; by default players see their own and other players' values but not NPCs'.
+- **Fog of war:** with line of sight on, ground a player has already seen stays visible as a dimmed memory (**Fog** button; **↺** forgets it for everybody). The memory is a small mask per player and lobby, the dim picture is made on the server, so players never get pixels they have not seen.
+- **Sight range:** the map's value is the default (map editor); the number next to the Sight button changes it live for the lobby (reset when you switch maps).
+
+### Sight groups and revealing far away areas
+
+- **Sight groups** (Lobby actions, DM): players in the same group (A–D) share what they see; "Everyone shares sight" / "Everyone alone" are shortcuts. Tokens and ground seen by one member are visible to the whole group.
+- **👁 Reveal** (DM, line of sight on): click the spot the view starts from, then click where it ends (distance = range, direction = where it looks), pick the cone width and who sees it (everyone or chosen players), then **Reveal**. Walls block it like any other view. The area stays visible until you press **Hide**; afterwards it remains as dimmed memory (fog of war). Everything is computed on the server, so players only receive the pixels you showed them.
+
 ### Maps, tokens and line of sight
 
 - **Maps tab** (top navigation): all your maps with preview. Upload PNG, JPEG or WebP (up to 12 MB, 30 maps each; the server checks and re-encodes every image as WebP, max 4096 px per side, into `db/maps/`). **Edit** opens the map editor, **Share** gives other users access by username (like characters: they can put the map on their own table or **Copy** it, but not change it), **Duplicate** copies a map.
@@ -126,6 +157,21 @@ The lobby page is built for desktop with three columns: the **character sheet**
 
 Players only see a short card of the other players, never their sheets. Guessing join codes is rate limited. Deleting a character takes it out of the lobbies (the player can pick another); deleting a lobby does not delete characters.
 
+### Scenes and props
+
+- **Scenes**: every map you put on the table becomes a *scene* of the lobby. Switching to another map (or back, in *Lobby actions → Scenes*) first saves the current one - token positions, HP and conditions, doors, explored ground, revealed areas, sight settings and the running fight - and restores the other exactly as you left it. State also survives pauses, since the table lives in the database. Per lobby up to 12 scenes; rename, delete, *Save now* and *Save a copy of the current table* (checkpoint) are available. Only one scene runs at a time (no simultaneous split party).
+- **Edit live**: the map editor can be opened for the running map. Walls, grid and sight range apply to the game at once; the prepared tokens are only used the next time the map is put on the table.
+- **Visibility in the editor**: the 👁 button beside each prepared token toggles "hidden from players".
+- **Props**: decor tokens (chest, barrel, table, chair, bed, door, campfire, tree, rug, stairs, ... 19 built-in drawings, plus your own PNG/WebP uploads up to 3 MB, 40 per DM). Add them in the map editor (*+ Prop*) or on the table (*+ Prop*); drag like tokens, size width/height in squares, rotate by slider, 45° or 90° steps (also in the right click menu), hide from players. They are drawn below tokens; players cannot move them.
+
+- **Prop library**: the *Maps* page lists all props (built-in and your own) and lets you upload, rename and remove your own ones.
+- **DM notes**: NPC tokens and props have a "Notes (only you see these)" field (map editor and table; e.g. the contents of a chest). On the table click the token to edit; a 📝 marks tokens with notes and the text shows as tooltip. Players never receive notes.
+- **Fog without walls**: sight range and fog also work on maps without walls (circle around the token). Sight needs walls or a range above 0; the explored memory is now stored at up to 1024 px.
+
+- **Map ping**: everybody (players and DM) can point at a spot: double-click the map, or press *📍 Ping* and click. All see a ring in the pinger's colour with their name, and hear a short ping (rate limited to one per second and person). The DM can switch the sound off or upload an MP3 for it under *Lobby actions → Sounds → Map ping*; players can still mute sounds for themselves.
+
+- **Measure, areas, markers** (for everybody, buttons above the map): *📏 Measure* - click start and end, the distance in squares is shown to the whole table for a few seconds. *⬡ Area* - spell templates (circle, cone with adjustable angle, line with width, square) in the colour of whoever placed them, visible to all until their author or the DM removes them (list top left, DM can clear all); they disappear when the map changes. *📌 Marker* - pins with icon, title and note on the map. Markers are private to their author until "Show to everybody at the table" is ticked; the DM can remove shared markers. They belong to the map, so they are back when you return to that map.
