The ghost watched as the boy on the broom circled around him, casting a old spell upon him. He gave a deep, guttural laugh. "Such base magic," he growled. He began to incant something, the words were foreign to the ears of the others around. Runes on his shield and sword began to glow in a ghastly glow that outshone the rest of his form, then he smashed forward through the barrier. A shattering of ethereal glass exploded into the room, passing through the students painlessly.
He did not care that they were trying to leave, he would rather have it that way. Though he would like to engage in combat, he was rusty at it, not having fought for hundreds of years. "I am Conri Mac Giolla Ri, warrior and general of the Tuatha De Danaan, adviser to Mac Cuill, Mac Cecht and Mac Gréine, last true High Kings of Eire," the ghost expounded proudly. "A more appropriate question," he stared right at Ford, "Who are you, young wizard, to question me?"
He ignored the boy on the broom, letting him proceed in getting them out of his domain. He was unconcerned with them escaping, the one speaking to him seemed curious enough with why Conri was here, he had no worries of them leaving.
