It might not exist. There's almost nothing on the place that I can find in the existing lore, aside from it showing up on the map. It's not even mentioned in the pocket guides. So, maybe not? I'm honestly unsure.
Dusk was definately planned. The Beta datamine from ESO which was supposed to include Summerset, explained a questline in Dusk. Where the Maormer grounded the planet Auri-El (hard to comprehend for us at this point) and the player had to restore it. Even Elder Scrolls Wiki took this over and you can find that event there. Well, the Wiki's have to be rewritten

Auri-El is my lord,
Trinimac is my shield,
Magnus is my mind.
The weird thing is that the Boat House description talks about it being "west of dusk"?
They have "Dusk Keep" around the area dusk would have been. that's it though as far as I can tell? It supposed to be basically where that mountain is that you cant get up right behind dusk keep...
