Loc: Crystal Forest
A stand of branching crystalline structures resembling leaf-less trees. They shimmer in the sunlight and distort the image of those passing by on the other side.
To create the map, drop a handful of dice and draw trees where they land. The value of a given die indicates the tree's size: it can break into that many large chunks, worth 1000 silver each.
When a tree (or chunk) is touched, it emits a loud vibration. The vibration in turn activates 2d6 more trees in a circular area. All hearing entities within the area roll a DEX save to cover their ears or take 1 damage per activated tree.
