I recall that Crius also had stats in 2E, in a Planescape book of short adventures... I'd point you to which book it was, but I can't remember the title...
BTW, that adventure doesn't say a whole lot about crius that we didn't already know. it does, however, talk about his home and how he behaves in it, and that is pretty interesting.
looking at the gravorg to see how we can make use of its powers...
Edit: D'oh! while thinking about crius, i noticed that i forgot to list prometheus' languages, and i forgot the "natural weapons count as epic for DR" line from some of the of titans - time to edit! should we give more than Abyssal, Common, Celestial, Draconic, and Giant to prommy?
