So my #dungeon23 megadungeon The Blades of Gixa continues to grow, with a new Documents section, currently featuring two in-world documents, the Baths Plunder Proclamation and the Highfleet Embassy Proclamation.
They're appropriately florid, so depending on taste they can can be used as-is as handouts, read aloud with some pomp, or DMs can just summarize and describe their effects. Each has a bunch of notes along the side for DMs, to contextualize them and describe in plain language what their ramifications are for the game world.
The Baths Plunder Proclamation is basically the fundamental OSRish adventure hook for the dungeon: the noble that rules the island above the dungeon puts out a call for adventurers to come delve beneath, clear out "dangers" (some of which are rival factions), and recover treasure for her (she lays claim to everything beneath the island). She offers big rewards for both--in fact, adventurers get to keep half the loot they recover for their trouble! (Players will, of course, see this as a 50% tax on their hauls, and they will plot and scheme endlessly to get around it. At least that's how it's gone in playtesting.)
The Highfleet Embassy Proclamation establishes an embassy on the island for the Highfleet, a society of ship-bound elves that threaten the Grand Admiralty, this world's hegemon. Is this a good-faith normalization of relations between rival powers? Of course not! Both sides bring various ulterior motives to the agreement, which your players can get deeply embroiled in (mine certainly have). Some of these secrets can lead inquisitive PCs deeper into the dungeon and towards some profound revelations about the nature of this world...or maybe it's background fluff and their greed will do the work. Again, up to how your table runs things.
The last image shows revisions to the Town of Baintoch spread. This is the town that sits atop the megadungeon. Playtesting showed me that the way I'd distributed information on the town spread wasn't really working for me: the original spread tried to cover both the town itself and, in an inset, the entire island it's on. Both locations suffered for it: the town lacked space for the encounters and more fleshed-out descriptions of services that would make it more runnable, and the island map was just too tiny and its keying too minimal to be useful. So I broke out the island into its own page, and updated the town spread to be much more useful, with day & night encounters, and more useful descriptions of the town's various services.
