It occurred to me that the possible heirs to the Empire wouldn't conveniently all be in Cyrodiil, so I had Taminwe visit Senchal while the player investigated Leyawiin. I couldn't have her do all the junket trips, so I wrote a piece of the story for the Fan Fiction section that has my reporter going over the border into Skyrim to investigate a potential claimant. Since the location of Falkreath is so close to the border that the land (and trees etc.) already exist on the Oblivion map, I decided to make it playable and build a town there. It means that you have to turn borders off to play there, but it doesn't have to be a required quest in the series, any more than you need to add the SI parts.Map of Falkreath in-game
There are four homes, a smithy, a tavern, a chapel and a guard tower. Although the story crosses over with my Mountain Riders, I don't want to make the mods depend on each other, so there's a bear trainer living in Falkreath as a reference to the other mod, but no shared characters. Jokull in the other mod talked of going back to Falkreath after delivering Claudia's bear, but he won't be there. He's a merchant, so he travels a lot.Bear (not quite Bare) Trainer
The City guards were going to be Nords, but I discovered that all the dialog for city guards (including "criminal scum" references) was restricted to Imperials, so they got changed. I used the Falkreath insignia from UESP Skyrim to overlay the Leyawiin Stallion and produce a uniform for them. There's a single-cell jail in case you need it.Falkreath guard uniform
As well as the two characters of the story, I needed a few more residents, so there are about a dozen NPC's, all of which needed dialog, AI packages, etc. I'm still working on the script for the quest, which has a few thorny problems where I'm trying to do something new.
There's more I could add, but I'll save the rest until you've read about it from the reporter's perspective, and I can explain what changes between the fiction and the playable.
Edit: I decided to make this a bridge mod, using the other two as masters. It was just getting too difficult to avoid using the NPC's etc. from Gweden and the Bear Riders. So Jokull may show up later, and other characters like Gudrun and Taminwe can play a part in the quests.
