The dragon

With Neb's spellcasting and apparently forgetting about the wild magic his familiar caused he was quite surprised to notice all three of them sinking in mud, instead of just the intruder, there was also a roar and a stretching/popping sound from behind him as his spell released the drago-bun from it's spell. the bonespawn had the creature in it's mouth already at this point and was not at all happy about having a rampaging dragon inside it's mouth, before long both creatures were near death, and as the dragon finished with a wicked claw swipe across now almost slonelike fless he felt the bonespawn's life-force flee, knowing he was also near death the dragon used a spare second to cast protection from chaos, and then a teleportation spell to remove him from the tower.

OOC: I know the tower cannot be broken into with most magics, but I'm assuming it's a defense mechanism to keep intruders out, not prevent them from leaving. PM me if I'm wrong and I'll edit my post.
