Drag to pan, wheel to zoom. Select drags objects. Roads auto-connect towns (dashed) — drawn roads replace them. Road tool: click to chain points, double-click (or Esc) to finish. Erase removes the object (or drawn road segment) under the cursor.

Rerolls the underlying terrain — continents, mountains, lakes and biomes — as a fresh base map to build upon. Everything you've placed (towns, camps, roads, elevation edits, templates, quests, biome tuning) stays and re-conforms to the new ground. Saving applies the new base map to the live world: standing structures are wiped like a cycle reset. Per-biome vegetation & wildlife live in the Biomes editor (link above).

Blank = default. Applies to this world only.
