The Great beast would be perfect for the Rage of Demons story line. If I didn't have the WoTC huge / gargantuan Orcus, i''d pick him up too. I'll have to see if my local store has the 70/80 mm bases. I see what appears to be pegs in the bases of the pics on the site. Are his feet notched for it?
Many of the demons will come in handy. I like the fighter, reminds me of one of my first minis of the game back in 1986ish when I get sucked into D&D by my friends. I bought that 3 fighter pack from Ral Partha I believe, that shows the 3 stages of the class, low mid and high level fighter and the helmet was like Thorismund. With that said, Caldwell also caught my eye, good stuff.
