Giz X'Tin Ranger epic turn in NPC

[fohkure]

I've tried to track this guy down for the past couple hours. From what I can tell, he's supposed to spawn at 10pm-ish game time and wonder in kind of a circle, then despawn at some undisclosed point in time?

I've been in his wiki location between 8pm-1am game time 3 cycles and a row and nothing. I'm a level 57 ranger with max tracking, so I'm pretty sure i'd catch him if he was up.

Does anyone have any insight into this?

Thank you,
Chris
