What's up with Sir Lucan?

[alexja21]

The wiki says he is on a 7-hour timer, but I've been sitting here for hours at a time (admittedly never a full 7 hours in a row) and keep an alt parked at his spawn point to check in 4-5 times a day, yet I have never seen him. None of the guards around him are ever camped and I never see anyone sitting nearby killing guards so I don't think he is just being killed 3 times a day. Does he despawn after a very short period of time or something?
