"Telogrus Rift" scenario complete
Umbric and his blood elves were cast out of their home for their pursuit of understanding.
I know the dangers of the void better than most. We should lend them our aid and ensure they don't do anything too foolhardy.
This rift will take us to their current location. I hope we are not too late to help them.
