Not precisely sure what is going on, he sees his companions attack the withered old man and determines this is good enough to determine the man must be some kind of threat. A quick scan of the room and having heard the massive explosions, Minathiel determines a mage of some nature.
Flying up the intervening distance, he hovers in the air, 10 feet above the mage, just out of reach, but within the reach of his sword, should the mage foolishly attempt to cast or leave.
"I apologize for my tardiness. I would surrender now, mage, before things become difficult."
With that he begins chanting, gesturing with the hand not holding his great blade, calling upon diving magic.
[sblock=OOC]Okay, now things get... interesting.
He takes a move action to fly 10' over the head of the withered man. This should threaten him and every hex around him due to the reach on a large creature. This is of course assuming the ceiling in the throne room is large enough. The point of this, short of a 5 ft step, he should provoke an attack of opportunity if he should try to move (moving from one threaten square to another provokes one, even on a withdrawl) Well unless he can tunnel of course.
He takes a standard action to cast Anti-Magic Aura, defensively (not rolling, can't fail). Again encompassing the mage and everything around him. (10' emination) Since epic spells (that is spells that are cast using the epic spell casting feat) are not automatically suppressed by anti-magic aura, I took the liberty of rolling (1d20 +20 vs 11 +23)
28 and 23 Minathiel's epic spells are unsupressed.
