"I have rarely seen such shameless displays of power. I believe your battle here is over- cease this before you rouse the attention of the Institute.... Gentlemen."
Necromonger watched the battles off-hand and generally did not pay them heed, but having beings toying with arcane powers as dangerous as this demanded his attention. His Companions were moving into position to restrain the combatants physically, amidst the maelstrom of energy. Gigantic walls of glyphed and warded iron emerged from the ground at the summoner's behest, encapsulating the area around the two problem combatants. This was of course thanks to a control device of the Institute's, augmenting the conjurer's wall spell.
"While the sparring grounds gets its fair share of explosive combat, there are regulations as to how much power one should reasonably wield- and how much one can use it."
((... Feel like butting in. A display of power like that would definitely warrant the Institute's attention, I think :P ))
