(I apology for the text choices this is my first time ever doing this comic style)

He had a hard time seeing the tree burn down, for him it was the reason why he even became a demon hunter the in the first place it gave him courage, he witnessed the first and second invasion from the legion he could not take it to see a third one. He hoped by becoming a demon hunter no other elf will have to do the same and now it pains him to see them all follow a path he did follow decades before, a desire for revenge, he kinda blames him self for it.

Before all this he did not had the chance to experience it but to have good memories seeing it growing from afar and when returned he did his best to go there ( but night elfs being night elfs made his life nightmare) he managed to stay a bit there under heavy watch when they needed him for hunting down any demon left on Azeroth ( i work on exploring that part of his story tho)

fan fact: before he leave teldrassil he took whit him a small vine from it’s growing state that even today still fresh as a reminder for who he fights.

@vaard i hope i do answer the question :;;;v
