Changed? Syrlya assumes that means changed the way that Rita's and Strange's has, and not just an influx or reduction of the same magic.

Still, it sounds like nobody has a real solution to the whole 'possession' thing. He still doesn't approve of the way Solas has described their societies handle it, but it isn't a threat to take lightly, either. Rock and a hard place.

"It sounds as if anyone who practices magic is kept under close watch." Except, apparently, apostates. "What about yourself? You don't sound as though you fear those spirits."

Either he's entirely confident about not getting possessed, or there's something else.
