There is a male Norn NPC Gardener just outside the door of the Great Lodge in Hoelbrak. I’ve heard the voice on a couple other NPCs scattered throughout the game. I dunno who the voice actor is, but he sure sounds like Leonard Nimoy to me. But the Gardener’s hair is covering his ears, so I can’t be certain.
Build a man a fire, and he’ll be warm all day.
Set a man on fire, and he’ll be warm the rest of his life.

The title plus the comment plus your signature quote…well, that’s a lot of funny right there.
Thanks Hamfast!
