What are the origins of the Tolkien Orcs/Goblins? What do they look like?
Twisted spawn of elves captured by Morgoth in one of the early wars. They are ugly.
If orcs are descended from elves are orcs immortal like elves if they are not injured?
That’s the assumption. There have been a few threads in Cafe Society about this recently, in addition to another one in GQ about the derivation of the word orc.
