Do you think Master Classes only have minions (like the Felt) when they come from singleplayer dead sessions, or would they have still have them in a normal session (perhaps weaker since they're on one planet instead of 14 of them)? On one hand, that does sound like something special that'd be unique, but on the other, they are called MASTER classes, so it's not like it doesn't fit.

It’s likely they’d get subordinates easily, but not necessarily, and Caliborn’s are special, being Leprechauns from a Dead Session and all.
