Lester is a 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 will reveal the full extent of his insanity and allow you to 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. After the hero opens up the Hive with the rune bomb, the next time he/she returns to Tristram from underground, Lester will have departed
