This is what happens when we mess with time... And let a bug go live.
The models for "Professor Echo" and "Dr. Aeon?" were accidentally reversed. Professor Echo should be the white-haired old man. This is fixed on the next update, the one that we're working on, but that fix wasn't propogated back to the branch on the live servers. I'll see if I can get this pushed forward.
btw - The time line you guys worked out is half right. While Bat'Zul is a threat, the beast beneath the mountain isn't what Professor Echo fears. All will become clear once Operation: DESTINY begins...
