From Duviri Fragments:

In all the ages of Thrax’s reign, only two strangers have ever known to come to Duviri.

The other stranger came far earlier in Thrax’s reign, before even the Bleeding Earth.

This stranger had haunted eyes and a downcast mien, and spoke of the Wall and the worlds beyond. He wore his hair like looped snakes, and his voice carried an accent unlike any in Duviri.

With the King’s permission, he constructed a great laboratory of light-smoking mirrors and Void-lanthorns, which he claimed was the match of one he had once owned in a former life. The island where it stood was known as Scholar’s Landing.

The time would come, the stranger said, when Duviri would be needed. There was work of repentance to be done, and he could not do it alone. What he meant by this I cannot say; and cannot now ask, for Scholar’s Landing vanished overnight.

But I shall watch, and wait, and hope.
