[@Hyyde322] Sounds good! If Yadira has been travelling, Gideon probably can't address a letter to her. But she could go to Nagaya looking to discuss that strange event, and Shiri will show her the letter she got.

As for teleportation, it's probably best to keep it limited, so travel won't be too convenient. Perhaps a mage with the right specialization (e.g. Eskel) can do short-range teleportation freely, but long-range can only be done between teleportation circles that are difficult to create and so are only in a few places. So Yadira and Shiri could hire someone to teleport them from Gwangju to Bradena.
