Coincidence? I think NOT!
As you said, we're probably on the right track. My only concern is, is this the final boss? Or do we get another item to spawn another boss which hasnt been released yet?
Hopefully another boss, but the one that spawns with the orb drops something nice. For example a black-white crystal, or something like that, but more than just one thing, this is a LOT of work to just get a dinky little crystal or some useless pet. I was looking through the gates where Titan 6 is last week, and it would be cool if one of them was open in NiM, and something related to the orb was in there, such as a giant area for the boss fight. But that's all just wishful thinking lol.
