I made a new character after Morrowind and instead of starting the main story quest right away, I just started questing and doing my own thing. I actually wound up going to Bleakrock and completing it entirely (saved everyone, etc) and completed quests in Stonefalls and Deshaan in full before I finally got around to going to talk to the benefactor and triggering the Coldharbour scene.
After completing the Coldharbour questline, I have a new quest in Davon's Watch available from Ruirik. He wants to send me to... Bleakrock! This starts the "A Beginning at Bleakrock" quest.
I am able to go to Bleakrock and talk to Rana, and she tells me where some of the townsfolk are...
Except they aren't there anymore. I'm in a phase where everyone is already saved and the buildings are burning, town is invaded, etc: I've already done all this.
The next step is to talk to Rana again, except it's not possible to do (so far as I can tell) because it wants me to talk to a phase or version of her that I cannot access any longer.
I also flippin' died from fall damage when leaving the Coldharbour area after saving the prophet, but we'll ignore that for now.
