So we know from a few posts ago that antlions lived in Xen. I guess the most pressing issue would be to deliberate whether they lived in the wild or in captivity. If they lived in captivity, the thumpers couldn’t have been for them. But if they did live in the wild, then maybe they were.
I’m leaning to think antlions lived in the wild in Xen. I mean, all the structures you see in Xen are factories, right? Maybe that’s all there is. Xen has this whole wild vibe around it. Even Gargantuas (whether tamed or fabricated) are left to frolic around. I can’t picture a set of cubicles for antlion care somewhere in Xen. After all, a Nihilanth in exile wouldn’t really care to play farmville with antlions… right?
Natural antlion colonies would seem to make much more sense. And with this line of thought, and having in mind how dangerously homicidal and overwhelming antlions can be, xenian thumpers are very, very believable, don’t you think?
