Not one that Heroic Fantasy Quarterly is putting together, but one we are interested in nonetheless.
Innsmouth Free Press is doing a Swords and Mythos anthology in early 2013. From their website:
Sword and Mythos. This includes any element of the Cthulhu Mythos (creatures such as shoggoths, characters like the King in Yellow, locations like Leng) combined with sword and sorcery (heroic fantasy). Stories can be told from the viewpoint of sorcerers or other non-traditional heroic characters, although fighters with brawn and brains will also be accepted.
