I really like altering the game world, or more specifically, how your actions affect the game world. Upgrading of the nursery, building of the temple,, the potential repair of Wayfort. Choices that affect ease of movement. Maybe finding and hiring an out of work construction crew (possibly minotaur engineers that were caught outside during the blockade). Having them start repairing the old Winter City bridge between the city and the Temple of Fire (more specifically to get to the old mines easier, since Ryn will probably want to curtail some of the Glacial Rift mining). That will allow easier travel from my visiting my Hellhound pups and the Winter City or Kitsune Den. Not sure if that section falls under the Marcher Baron's domain, but possibly would generate a small amount of tolls over time (like the Mallach Temple), granted by the Regent as compensation for aiding in the rebuilding of Winter City's economy (or just peripherally as tolls from increased merchant travel through the Wayfort because of the ease of travel with the new bridge).
No idea what costs, materials, or amount of time that might take to get a functional bridge built though, but could also add in an option for Winged PCs to be able to fly from one end of the old broken bridge to the other. Likely would require them to be alone (or maybe only a single companion if they could logically carry them); Brint is probably out. But that area already has precedent for having a lone PC in the form of the Snake Girl (Vatia) sleeping content. It would really just make travel from one map point to the other, ala the Livernius ferry ride in Undermountain.
