I've updated the Players Companion PDF for using Mythosa with OSE. There's no nice formatting here, just a straight export from Obsidian . I'll make it look nice later, I just wanted to get the update out. It's available on the Downloads page.
I was tweaking the Mythosa climate map and realized I'd never uploaded it here in the first place. I've corrected that issue; it's available now from the Downloads page. In other news, the Codex is being re-organized, and Player's Companion is being updated, and more posts are planned here in the future. Including "Why Race as Class is Superior" and "Reasons Why New Editions of D&D Suck". Stay tuned...
For a variety of reasons, I've switched from 5E to Old School Essentials . To that end, I've created a PDF for using Mythosa with OSE, including house rules, what optional rules are used, and similar things. The PDF is available from the Downloads page.
Very minor edit; the label for the Vhallosean Sea had somehow disappeared. This is pretty common, actually. Almost always when I edit something on the map in Wonderdraft somehow a label disappears on the map. Not sure if this is user error or a bug in the program. This had been sitting out there for awhile, but it should be fixed now. Still a program I highly recommend. Knocking around ideas for future development, though the only thing on the horizon at the moment is a new Mythosa Player's Companion for Old School Essentials .
