Good layout and setting. I get some Dark Sun vibes, which is neat-o. My honest critique only: too unbalanced for L1 characters. Random encounter sunlight attack that’s DC 18 DEX or 2d6 damage with no clear way to avoid it altogether, spike pit that is 18 DEX to avoid for some reason. Falling is is 18 CON or “you die.” Stuff like that. There’s so much of it.
