I am! Mine is also a fantasy, centered around the elements and an imbalance of space/darkness/night that threatens to throw the world into chaos. It's a lot better than I'm making it sound.
Like you, I'm also re-using some characters from a series of RPs I did through Middle and High school with a good friend. We've got a collection of 25 or so notebooks from those years.
It's been a chaotic month unfortunately and I haven't been able to write much. Not sure if I'll finish, might just scrap it this year and completely restart next year.
Good luck to you!
