Ah! Yeah, I regret not having an explanatory section somewhere!
The module is written in the second person addressed to the person running it :))
The warden is Ur - it's a clumsy attempt at a meta thing where the warden is in the position of being an in-fiction storyteller for the dungeon. Through whatever means: seeding hooks, rumours, etc, they bring the party here and hope to be freed. They have fairly limited influence beyond that outside of talking to the party at the peak.
In terms of how everything would fit together mechanically, yeahhhh this one really needs a playtest. I think I tried to make everything fit together a little *too* much, and I'm not sure how easy it would be for a party to interact with a lot of these systems. The Game of Ur in particular, having both the constrained grammar and vocabulary of the glyphs, is kinda rough. I think after the jam and a few playtests I'd defo love to write up a less obtuse explanatory document to make these things a bit clearer :))
