"It would be stupid if they aren't." Istredd's fairly positive they have a magical tracker on everyone. It wouldn't be hard to do and it would be the first thing the Brotherhood would do if they were the ones plucking people out of other realms. They probably would have thrown them in the dungeon right away too. Thorne and the Brotherhood have more than a few things in common.

Their movements are already pretty controlled by Thorne and he's gone no where that they wouldn't be able to find him easily. If there is a tracking spell it may be something they have to counter some day, that's all. It will be curious if Kyle sets anything off.

"We're definitely not going to tamper with it." It is too useful to take any risks with. "I'm fairly certain you're the first person the King has actively spoken to from our group." He doesn't know about the originals, but most people still around since then are the people who fled. Yennefer has her connection with the Queen, Stephen with Ambrose, and now Kyle with the King. Not bad.
