Behsten

Behsten is a human located in the War Room of Stormwind Keep, in Stormwind City. Behsten gives members of the Alliance access to an option that allows them to turn off experience gain in the game in any form or fashion. The fee is to turn on or off each time. He can be found towards the back of the room in a stealthed state.

Quotes

 * Gossip
 * There are some who desire to stop gaining experience from their actions; to forever remain at the level of strength they are now, and never grow stronger.
 * I can make this possible... for a fee, of course.
 * But understand this: Once you pay me, you will NO LONGER GAIN EXPERIENCE. None. Not one whit.
 * Should you change your mind afterwards and want to start gaining experience again, I can undo the process for the same fee.

Depending on if experience is disabled or not, one of the following gossip options will display:
 * (fee:, will apply Experience Eliminated)
 * (fee:, will remove the buff)

While standing around, Behsten will randomly emote some thoughts that are fairly common to level 19 twinks:
