Pepin is a Diablo I NPC, and is found to the lower left of town, across the square from Griswold. He is the healer, and will restore any character's health to full (if you click the option to do so in Diablo I), or simply talk to him in Hellfire). Pepin has a variety of quest dialogues, but is an essential player in just one, The Black Mushroom, when he sends you to find a demon's brain and takes it in exchange for the spectral elixir.

Pepin is thought to have died when the demons burned Tristram to the ground.
