The remaining armies of Valhalla gather at the nexus of reality as space and time crumble around them. Even when all is lost, the battle rages on!
Build Notes: Here in Virtualscape I've made the map using a lot more 7-hex tiles than I actually own. IRL, I had to rig some out of 1-, 2-, and 3-hexers to have enough. You might need to do the same. Essentially, there are 6 types of terrain here spiraling out from a central hub of molten lava. It's really not as hard as you may think to make. Once you start, the map practically builds itself. You'll need 10 7-hex tiles of each terrain type. There are standardized terrain features added to each arm of the spiral.
Setup: Starting zones are single any terrain type along one of the outer arms. Some have more spaces than others, some are natually more desirable than others. YMMV. Note that there are three arms (or sections) of each terrain type- Outer, Middle, and Inner.
Rules:
All normal rules for terrain types apply here.
--Use heavy snow rules.
Black Hole: At the end of every round, roll a d20 to determine which type of terrain is pulled in by the Black Hole.
1-4: Grass
5-8: Sand
9-12: Rock
13-16: Snow
17-20: Road
(Note that Lava Rock is never pulled off. )
One arm of the corresponding terrain type is removed from the map. Begin by taking away the entire Outer arm and working your way inward, (Outer --> Middle --> Inner,) each time that terrain's number is up. Any units standing on those tiles are also removed from play, victims of the Black Hole. If the entirety of one terrain type has already been removed from the map, reroll the d20. The Black Hole must be fed!
--If a section of the map is no longer connected to the central hub because all adjacent sections have been consumed by the Black Hole, that section and any figures on it are also removed from the map.
