Soloed with a 28 Champion.
Just walked up the the ancient stone table, right-clicked on it.
Two wargs came running up, one of them was Shadepaw.
Killed the weaker one first, then shadepaw...Killed him with only about 35hp remaining. Real close, but didn't have to use any heal pots.
My armour is pretty good for my level. 1950 or so.
