[Taqwus]

There's always the Pangaean Carrion Dragon, which does have recuperation if memory serves. It's not quite the 'traditional' dragon however.

Immobiles... well, there's the Fountain of Blood, which might be useful for jumpstarting a blood economy. There's the R'lyeh Void Lurker, which since it's alive can be turned into a mobile Wight Mage. The Oracle might be useful for an astral-9 blessing, while Mr. Flaming Skull has been pushed into F9/A9 by some although the scales will presumably suffer.
