Hmmm...maybe no one would be there except for logs that Revan and the Exile left? I suppose them leaving logs would make sense considering that they probably would know that someone would EVENTUALLY muster the courage to get onto Malachor. I would also assume they would want to leave something behind in case they didn't return...which they didn't xD 

Also, almost done! Going to introduce my apprentice near the end of this one!
