Now that Gweden Brothel and the Rumple Mod have joined at Falkreath, I'm (intermittently) working on more 4th Era stories related to the slow rise of the Thalmor. I don't see anyone playing for ten years of game time, so it won't reach the assassination of Ocato, or the sack of Nova Orsinium, but the events that led up to them are fair game. The FF already has Uzgash - Gortwog's daughter - taking refuge from the possibility of assassins by faking her death and moving to Cyrodiil. That needs to become a quest in the mod, probably without a bridge accident, and there's most likely fuel for more involving her six siblings. The eldest son will be named Nagorm after his grandfather but I haven't any ideas yet for the others.
I'm also thinking that
Marghak - Uzgash's mother - may follow her daughter to Cyrodiil for safety as the situation in Orsinium starts to get perilous. She's head of the Guild of Prostitutes in Orsinium, so that gives her an excuse to visit the Red Dragon Club on business. My current ideas are that Ocato is covertly supporting Gortwog, while not wanting to take sides in any disputes among the petty kingdoms of High Rock and Hammerfell. That will account for the Legion rescuing refugees when Orsinium is sacked and leading them to Skyrim. The co-operation has already brought the
Helm of Tiber Septim back to the White Gold Tower, and that sort of quest could done again. I.e. Orcs find clues to something, player fetches it.
I invented Marghak for a Daggerfall mod, but haven't really given her a backstory. I'm thinking that she was an orphan, raised by a coven of High Rock witches, who then became a prostitute somewhere in the area that Gortwog won in his duel with Lord Bowyn.
At least one of Gortwog's children should have gone to the Summerset Isle, and may become a victim if the Thalmor find out who he/she is. No ideas on how to bring the news to the Imperial City. I already had another brother return from Black Marsh when that province seceded. The attempt to kill him was part of the reason Uzgash was sent to Falkreath to hide.
Meanwhile I'm playing in Elsweyr and Valenwood, looking for ideas just over the borders. I may even set a quest or two in those provinces, for those who have those mods.
