Grand vision belongs to me as much as Kaisos, so don't worry 'bout that.
Smaller works would be fine, and I wouldn't worry too much about grammar troubles with longer works, since that's what editors are for. However what I really think I'm looking for is for stuff with a high level of background details like your post about the Esper Organization.
I would have some spare time around mid-June. I wouldn't mind writing smaller scenes to help relieve the pressure; but I haven't got the confidence to do the larger ones. Honestly, you can see how I lose my grammer when I write the longer works. The major concern; how compatible would the stuff I write be with Kaisos's grand vision?
