solid work! imo the layout + flow of information shine here. the whole thing is clean, easy to read, and sells the old book feel nicely. well put-together, especially for a first module.
high: the observatorium read-out text. great setpiece. it's a spike of energy that shifts the mood in an otherwise subdued dungeon. i also think it's cosmically funny that the thaumaturge gets the reputation of "keeper of the ledger of fates" but actually his statue does the keeping while he hangs out in his hot tub of ecstasy and terror.
low: the constellation list is cool, but i don't love making the puzzle elements random. it's a missed opportunity IMO. little details like being specific about the thaumaturge's birthsign add depth of flavor that piques my interest as reader and GM. so, i would've liked to see that!
in-between: the vault statue can easily kill people with its evil gas. but the corpse next to it seems to be both desiccated and bludgeoned. why did the statue do that. what's its deal.
