My Tunnels & Trolls PCs advance on the ghoul king and his minions... just as Leadfoot, the dwarf PC, decides to turn against the party and ally with the ghouls!
The big ghoul with his fist raised on the right side is actually a Slayer from the Wizards of the Coast Diablo 2 Monsters set, customized a bit (removed the horns, elbow spurs, and axe).
The human-sized lunging ghouls are from Mantic Games.
The hard-too-see brown things near the "ghoul king" are plastic dinosaur skulls from Safari Limited's Dinosaur Skulls Toob.
The green wraith-like creature near the "ghoul king" Ringwraith is the PaizoCon exclusive "Festering Spirit" miniature (a repaint of the Spectre from our Heroes & Monsters miniatures set).
