Been a while since the last update, but Good News, Everyone!
All the documents on the front page have been completely redone (I know, I know, again) to form what is henceforth the Freshman’s Handbook. This is the basic kit for Sigil Prep, with new supplements to follow. Yes, it only covers the basics (Dwarf/Elf/Halfling/Human, Cleric/Fighter/Rogue/Wizard), but it covers them thoroughly, with the other elements to follow.
Hang tight, kids. Sigil Prep is about to get good.
(Edit: Reuploaded the “Classes” document which previously included some text that refers to rules I ended up not using.)
