Tomb demon in Indinera Glade

[Beldarius]

I haven't seen any mention of this in the walkthroughs, so I'd just like to confirm something... this demon wasn't needed for any quests, right? I opened the tomb when I first entered the glade, but it seems there was nothing else inside apart from three ghosts and the demon (which I've already killed).

The demon and ghosts are covered on step #25, though you can access and clean out the area much earlier. It’s just an optional area with a couple goodies I believe. Specifically, the Steel Breaker drop from the demon and the Gaia Dust in one of the holes.

It’s not connected to any quests, nor am I aware of any reason to wait and do it later.
