Lester

From Diablo Wiki

Lester is s farmer who used to live where the hive has popped up. He can be seen talking to the cows and the other town people think he has gone mad...but they feel sorry for him because he lost everything. He gives you the rune bomb quest which allows you to enter the hive. Using the command file you can do the long awaited cow quest! (see Complete Nut for details)

Unlike the classic Diablo NPCs, Lester does not have any gossip and can not be asked about quests.
