http://en.wikipedia.org/wiki/Cthulhu Now dont you guys think that the god of all firk deserves at least 1 rune, or a reference to him on a rune? Also if you released an Old Ones expansion it would help attract fans of the Cthulhu mythos to this game, which you could advertise here. https://www.facebook.com/iaiacthulhufhtagn?fref=ts I am not very religious but Cthulhu is one of the 2 gods I worship, and its easy to see why because of how magnificent he is.
I am telling you whoever originally made the firk got inspired by Cthulhu. Anyway Cthulhu needs to have 30 damage if you are ever gonna give him true justice.
I'm almost 50% certain that the Firk were inspired by Mindflayers, not Cthulhu. (Who in turn were likely inspired by Cthulhu, but that's totally different)
As @SkeletonKing said, Firk are based on Mind flayers (Illithid) which are based on Cthulhu. Mind flayers use psionic abilites, where Cthulhu was never credited with any kind of psionic power. Firk are different from both in that they are natively good, not evil. Also Poxanthru is its own realm, there is no lore stating that it is in any other realm. I would prefer that we keep Pox lore unique. While there are many similarities to other fantasy realms, Pox is pretty original as well. Cthulhu is supposed to be the size of a mountain, so he would not fit in the game either.
I don't know much about Cthulhu, so take what I say with a grain of salt. (I did however just start listening to a sound book called Necronomicon from Lovecraft.) If I am not mistaken, Cthulhu doesn't have a form human brains can imagine. The depiction of Cthulhu is just a depiction of how different Cthulhu might look from what are used to. Cthulhu is generally not considered a one being, but instead an idea of a being. Giving Cthulhu a physical form and being able to fight it goes against the very idea Cthulhu stands for. The scary thing about Cthulhu is that humans would have no way to battle Cthulhu, as humans are seen as insignificent and bound by physical form. If Cthulhu is in the game, my guess is that Cthulhu is the bound that all Firk share. Extra for those who might have missed it. Lovecraft books are often about an impossible crime, often involving a detective. Look at the art of Firk Executor. Realize the awesomeness.
Basically what soulmilk said. The only way I could imagine a direct Cthulhu reference ingame was as an Avatar that can only transfigure if you control 5+ Fonts (i.e., would most likely have won anyway), but that has some interesting feature while not transfigured.
You are all forgetting about the greatest of the Deep Ones. Not much is known about him but for a single passage in the Necronomicon:"Absorbent and yellow and porous is he"
