CoreCommander

These: They came with the CoC TCG core set (set of 10 or 12 I think) of which I had 2 and an additional 5 in a separate bag along with 20 of the small Cthulhus. I use them as terrain in AoS. The bigger ones are about 3 inches high while the smaller ones stand at 1" and are more useful as board details and decorations. I even had home rules for the statues warping space and time ("Broken Space, Broken Time") and apocalypse hour clock based on the forces attracting the attention of the Old Ones by fighting there.

Ah, these ruins. They'd go nicely with the arcane ruins set. Also I have about 20 Cthulhu statues (don't ask) so I can make a proper underwater city
