A Guide to the Planes in My Homebrew Setting

Many years ago now, I started a new campaign. I was designing the campaign based on player suggestions, so I didn't know where it was going yet. But I knew my tastes and my style, and I remember telling a player who was new to my games that I run a pretty low-magic world. That player would later tease me because the opening session of the campaign would feature a displacer beast accidentally let loose from a circus--not exactly a low-magic world after all. I've always resisted high-magic for reasons related to my aims as a DM, but after my most recent campaign, I think it's time to admit that I am not much of a low-magic DM after all. 

And if I'm going to get comfortable with being a high-magic DM, it's time to get serious about what exists outside of the mundane world. That's why this guide explores the different planes of existence in my homebrew setting. Some of these will be adaptations of what already exists in much of the writing about D&D, and some will be more or less fresh ideas. But having had my players visit the Fae realm in the final session on the campaign helped me realize how badly I needed to think about all this, so here is a guide to all of the planes of existence in my homebrew setting.
