Seems like an unreliable source unless multiple posts have the same information.

It begins already with

NOTE: This is a somewhat outdated guide, scroll down further for a more recent version.

You got: http://www.thesafehouse.org/forums/s...41&postcount=1

That states:

- Eldreth is a totally rondom spawn spanning anywhere from many hours to a few days (Real Life Time).

And

- Yendar is a totally rondom spawn spanning anywhere from many hours to a few days (Real Life Time).

Go down few posts: http://www.thesafehouse.org/forums/s...45&postcount=5

- Eldreth spawns every three hours after despawning.

And

- Yendar spawns 3 hours after Renux has been killed last.

Also about when handed Scribbled Parchment

NOTE: Yendar no longer despawns after giving him the scribbled parchment.

So if we really want to be correct, it technically should be a 3 hour timer and not an 8 hour timer.
