Rooms, connections & controls

Hover over a room name to preview its last observed description. Click or tap the name or preview to keep it open; click outside or press Escape to dismiss. Drag to pan; pinch or use + and − to zoom. With the map focused, arrow keys pan and Home returns to your room. Start typing to enter a game command; Enter returns to the command box. Escape closes the map. On desktop, drag the divider to resize the panels.

Arrows show travel you have made, not every possible exit. Room numbers distinguish places with the same name. Levels are relative to each area's first room; unusual routes may connect established levels. Positions are schematic.
