Question regarding Brother Zephyl

[Tarnot]

I am relatively new to the server and am in the process acquiring a pair of jboots. I've been hanging out on the Hasten spawn path for about 40 minutes now and Brother Z has taken several strolls by me. Through the search function, I've not been able to find any definite answers on whether or not Brother Z despawns; some say that he does, others say that he does not and both claim that their case is "as intended."

Does anyone have any first-hand experience with his despawn time?
