'Tales of Ruma' is an anthology from Azure Keep, and they're looking for fiction set in their shared world:
Ruma is an alternate Roman Empire set on an alternate version of Earth where the gods and magic are real. The RPG is set at the beginning of the Ruman Empire, somewhat akin to 0 A.D. on Earth. Hellas (Greece) has been reduced to ruins as Hellene magi opened portals to Hel and the Outer Realms to stop a Persyan invasion (known as the Sundering). Aegypt, also known as the Eternal Kingdom, has been ruled by the Pharaoh (rumored to be a Lich) for centuries. Their armies are archaic but augmented by magi and massive stone constructs. The Kell or Kellic people (based on Celtic society) and their mystical forests encroach upon Ruma from the west. Other cultures include the Normen (precursor to Vikings), Heermen (Germanic tribes), and the missing people of Atlantys.
Submissions close September 30, and they're after 500-5,000 word pieces, paying 6USc/word and contributor copies!
