Thats a lot of militors...
I dont think these possessed weapons fit in very well in a non-medieval playthrough but that legendary zeus hammer with minor psychic bonus would be a nice upgrade for Grug.

Speaking of Zeus hammers I plan to now build a gravship and embark on destroying the mech hive. I will eventually leave behind my colony and some lesser pawns. Is it better to not build an anchor and glass the tile or just leave and then abandon? Thematically I want to just leave them behind to carry on without my oversight. Is there a difference in mood penalties at all?
