Caution was the watchword. Magneto knew better than to think Pietro hadn't already raced here to warn his little X-Friends (in fact, he was counting on it). He touched ground before the gates, Wicked still floating lazily along behind him. She'd wakened during the journey and he'd had to fashion a new band to slap over her mouth and shut her up. A tantrum from her wasn't anything he cared to listen to.
Magnus regarded the gates for a moment and then flicked them open. It was easy enough, too, to dismantle all the high-tech lasers that began firing the moment he stepped foot onto the school's gravel driveway. So much metal in their defenses. Next was a hail of bullets from unmanned guns sliding from hidden compartments on the roof. Ah, the 'Welcome Wagon.' He made short work of those, too. An alarm blared, alerting him to the fact that they were in lock down. Magneto continued up the drive to the mansion at a leisurely pace. There were cameras, he was sure, following his every move, feeding back to the X-Men anxiously watching from their bunker. Cowards.
"Come out," he demanded, halting before the front steps and gesturing so that Wicked, floating horizontally, was flipped upright to hover beside him facing the front doors. "I've got something you want and you, I think, have something I want. Try an attack and these bands will slice her to pieces. Don't test me."
