Well, technically I'm working on two. The first is a remake/redo of Cross my HEART, fleshing out the world, making some tweaks to the story and the lore, and generally trying to fix what mistakes I made the first time. It's looking good so far, I think, and watching shows like Soul Eater and RWBY have given me tons of inspiration for the setting.
The second one has less to go by, but it focuses on the fae/fey from traditional western fantasy settings. There has been a war between the fae (the immortals who are closely in tune with nature such as pixies and treants) and the mors (the mortals who have abandoned this connection like humans and orcs). The players would be fae who seek to find a cure for their leader who has been poisoned by mors assassins, which will take them into wild and dangerous territory owned by the unseelie fae, creatures who attack even other fae on sight.
