In the first Well of Darkness quest, Buried Alive , there's this great little familiar that the Overlord controls, The Haunt. I had an immense amount of fun with this little guy and it truly annoyed the Heroes invading my turf. But eventually it got caught in the mine collapse after I failed to account for the distance it had to move when I saw some easy hits on a Hero calling my name - I'm not sure if I got suckered into that as a tactic to get rid of this annoyance, but it didn't really help them as they all died shortly thereafter anyway. So, while the Haunt normally ignores all obstacles I decided it was lost in the collapse and wasn't going to pass through all that rock and water.

Anybody played this any differently?

Yes, the official rule is that the haunt and all familair will be placed on the last available square on the board when their are is removed from the game.

The Haunt and familiairs will never leave the game.
