Revisited Red Belly mine and found spiders respawned in the now "safe" mine - attacking the workers within. I managed to save all except for a young lady who became spider chow. I then pushed on to Darkwater Crossing to pickup my old dragon buddy Derkeethus. Three hired goons showed up as well, but they didn't attack me - they just followed me like puppies and helped me collect some Jazbay grapes and defeat a blood dragon. I was beginning to take a liking to the three stooges but I knew that they had been sent by daughter Black-Briar (since I managed to pickpocket a contract from them).
Decided to hand in the grapes at the Sarethi farm first - took awhile to find the damn things, I had this quest before I fought Alduin (like 10+ chapters ago). Unfortunately the dunmer lady would not be able to make use of them as she and her daughter rushed to the aid of a wandering nameless khajit under attack by... the three stooges. Having forced my hand, I aided the farmers but could not kill the heavily armored warriors in time to prevent them doing painful looking finishing moves on them. Derkeethus did one of his own with his daedric axe as the finishing blow.
Marched straight back to Riften to confront the alchemist daughter about this and she feigned ignorance. However she let slip again that she wanted to become a necromancer and practice dark arts so without further hesitation I put an arrow into her face and tossed her body down one of the murky canals leading into the sewers. With that done we revisited Esbern, the last remaining blade as Mjoll was still MIA. He had no more dragons to hunt so Derkeethus and I returned to my Solitude home to rest up with the others: Njada, Jordis, Wynna, Rayna and Anni for whatever next adventures lie ahead.
There were still khajit caravans to stop, places to clear, and plenty of falmer to slay but they could wait for another day. With that I am taking another break from Skyrim - for how long? Who knows.
