River, at first, is only passing through the library on his way to Yseult's office. His boots are covered in mud: a tale of someone recently returned from reconnaissance work outside of Kirkwall. Some locales seem to be eternally drenched in rain. He's just here to grab a book to go with his codex when he notices the new blood sitting at one of the desks.

Right, making friends and keeping an eye on the rifters is part of his job. He changes trajectory and moves to pass by her desk.

"New?" he nods, a gesture toward himself. "River."
