Hello,
I have a Dawnguard-related question in regards to the people that you can get the hidden cache keys from and note to where the individual caches are located and I wanted to know - I've already returned Serana to Volkihar castle and declined Harkon's invitation to join them and already got Sorine Jurard and Gunmar for the group. If I had gotten that far, is it too late to go for the first of the few cache keys ? I've tried walking all over the place to look for Lynoit's corpse, but I can't find him and I don't even know of any good spawning points to go look for. (Same for the Dawnguard folks who want to leave, apparently.). I know with one of them, there should be a vampire attack going on and you CAN save the person, and I've tried walking around at night, but I just can't seem to find any of the Dawnguard people.
ANY help would be greatly appreciated. A huge thank you in advance from a huge fan of Skyrim.

P.S.
I've lost SOME interest in Elder Scrolls Online, but I get bullied on there, sometimes.

Update : I already found all of the Dawnguard cache keys and boxes (And I got some extra sets of armor and weapons too. ).
