Background:
Scrub covers most of the Island map in SoB. It has no movement related affect, just a range related effect.
Can space traps be played on scrub spaces? Spike Pits would seen very logical and thematic. Crushing blocks less so, but no more or less that on the non-scrub island spaces like sand (explanations range from meteor strikes and aircraft 'waste'(!) to off-map catapults or - more likely - tree-related trap effects (trip a wire and a line to a bent tree releases, flinging a boulder or releasing a swinging tree trunk etc)).
Question:
Q. Are 'scrub' spaces counted as empty for any purposes? Can 'space' traps be played on scrub spaces? Can a Leaping figure end its movement on a scrub space? Can a normal figure end its movement on a scrub space?
A1. Scrub spaces may be treated like Corrupted Terrain. Scrub is treated as an empty space fr the purposes of playing traps. Once a trap has been played on it and left a token, it no longer counts as scrub.
A2. Scrub spaces are not empty for any purpose. They have scrub in them! Therefore you cannot play space traps in them, or finish a Leap Move* on them.
A3. Scrub spaces are treated as empty for the purposes of any movement (including Leaping), but not for playing traps. Of course, if a figure or other token (like a villager for example) is also in the space then it is not 'empty'.
A4. some other combination...
