I have two subsector maps ready, the first to transcribe my notebook paper depiction of the border region the first two sets of PCs were adventuring. The new one is for the further off section of the (somewhat heavily-) implied setting. I can't see a reason not to include a spacewarp connection between the two maps, so, that will likely happen.
This work has helped solidify the procedural chargen of Urutsk, especially the class-level based mini-game which we haven't used in ... has it really been, 'years'? The homage system is roughly half-scale mechanisms-wise, and there is even a quasi-percentile chart to aid in the conversion between systems (and time periods). It is especially important in bridging Porphyry: World of The Burn, with Urutsk: Worlds of Mystery, both mechanically, as well as thematically.
As far as the homage system, I still need to finish worldgen, add ship components/systems, and include a few spot rules. I'm not sure if this will actually come in under my original page count, but it should be close.
