Question about orders and defending

[Kobal2]

Nope, only LA C'tis gets undead priests they can summon with era-specific spells. EA C'tis can only reanimate by summoning some undead commander (usually a Mound King or Black Servant) and making it their prophet; but AFAIK even then it can't revive the Tomb Chariots that make LA C'tis so kick ***, only the usual soulless/longdead/ghouls.

All ages of C'tis also get unique lizard skeletons/zombies whenever they reanimate soulless and longdeads (both in and out of battle) but they're nothing to write home about: just one more HP, a tiny bit of protection for the soulless and 2 points of MR for the longdead.
