Warriv is a Diablo II NPC, and is an NPC caravan master. He is found in Act One city camp Rogue Encampment, standing near the stash, above or to the right of the firepit, near the center of town. He does not give any quests, but offers useless advice on most of them. His only real purpose is to welcome new characters to the game, and to offer passage to Lut Gholein once Andariel is defeated.
Warriv is the only NPC with a change of clothing. He wears heavy blue-themed clothes in the Rogue Encampment, and changes into beige desert gear when he arrives in Lut Gholein.
