The Mysteries of Vana 'Diel

[Septimus]

This is a tough one.

If we assume Doggvdegg fell into the Crystal line after the battle with him in the WOTG Sandy mission then it's possible he remained there in limbo until the Al'taieu crystal became linked to the system during the events of CoP.

It isn't exactly impossible seeing as Lion pulled off a similar stunt that sidelined her from the conclusion of Zilart until the post-CoP followup in Apocalypse Nigh.

Apollyon is the Greek word for Abbadon, which is Hebrew for "Place of Destruction" or "The Depths of Hell". Temenos originally meant an area set aside for the worship of gods, but has come to mean the plane of a deity.

I think that Limbus is one of the afterlives of Vana'diel.
