Radiant Crown Publishing produces Helios Quarterly magazine, which:
[...] aims to publish quality fiction, poetry, nonfiction, and art that illuminates the darkness. HQM wants stories and poems that grab ahold of a reader from the opening lines all the way to the finish line. Works that push boundaries, are succinct, and well developed are smiled upon.
We are shaped by our past and molded by ideology, but our convictions can be changed in an instant. Science fiction envisions encounters with the alien so horrifying it reshapes the world order. The horror genre shakes us to the core when it forces us to come face to face with forces beyond the scope of reason. Fantasy literature opens the door to the other, monstrous, evil, and sometimes all too human. First Contact & Conversions wants stories that confront situations that change us as people. Who are the prophets among us warning us of things to come? How do we handle change so rapid and all-consuming that the world we once knew vanishings?
They are open to submissions for two weeks each quarter (next in October 2017), and are after poetry, fiction (micro, flash, short stories and serials) as well as non-fiction (articles, review) of the science fiction and fantasy persuasion. Yes, they pay, ranging from 2-3c/word for prose (6c/word for micro fiction), and 25c/line for poetry up to 100 lines.
