Hey everybody!

*SPOILERS*

Just finished the "In My Time Of Need" quest.. I killed Kematu to save Saadia (or whatever her name is)!

But the Alik'r warriors that are in Whiterun to give you the quest are still there.. Will they be there forever?

they can be. consider them additional back up should vampires attack thanks to random occurrences from Dawnguard.

Or you can go stealth and kill them with a bow. the guards might look for the killer but just put your bow away and walk off.
