EG, I wouldn't start populating cubulus unless you've got nothing better to do. We started this thread because there was a suggestion about keeping the aliens/vampires separate (even giving the aliens their own squares possibly), so depending on the input of the rest of the community, we might want to let the invaders clear that square and start over. Also, I would rather have 10591 for cubulus or something equally rare, as re-populating vampires/aliens isn't as difficult a task (considering my digger lives permanently in vampire vacation).
I agree that I'd much rather have the centaur shaman (lvl 38) than the titan (lvl 40) for dragongrass because of the weight of that ruby wizardkiller, but also because it would allow lower lvl players to start collecting grass a couple lvls earlier. (And again, I seem to have a couple chars on the centaur's book, so I'll leave them there until we get this figured out, in case we need help populating the shaman).
Higher lvl monsters that I'd like are the
dimension carver
(lvl 68, dimension sliver), and the
dungavatar
(lvl 97, hydragen-carbids). Though as there are few players who could defeat the avatar, he's not as high on my list as some of the other monsters mentioned here.
Possibly the
old granitedragon
(lvl 39, dragon horn).
