I have not made it that far but this is what I found on Gamefaqs:

Hall of Echoes [FLHOE]
--------------
Location: by the time you can enter, it's marked on your map
-Kill all the Nest Dais to drop the barrier
-Fly into the giant orb to proceed to the next area

-You must defeat seven sets of opponents in the arena to proceed. They drop
legendary, unique, and epic quality items, but the level of the items is
extremely random (level 2 items can and do sometimes drop), and you cannot go
back to get them enchanted. It's extremely unlikely for any of them to be
better than what you have at this point, so don't waste your time trying for a
good drop.

-After defeating the last opponent, step through the teleporter to the east to
proceed.

-Fly through another giant orb to reach the final area.

-Regardless of how you proceed through the dialogue, the final battle begins.
