Hive

The hive of an Arathropiae colony is its center. It is constantly enhanced by workers and has hardly penetrable reinforced walls, making it hard to destroy. What makes it even harder to destroy is, that the Arathropiae rather would die, before letting you near one of their hives, so, in order to get to one, you will have to make a lot of them die. The question is, if you really want to get near it, since it emits spores, which will cause toxic effects if you breathe them in. The only reason to go near such a hive would be the strange anti-toxic effect of the spores, but trying to reach a hive while being poisoned is maybe more deadly than the poison itself.
