Myself and Lord Motochika are working on a history of this place since the arrival of first wave of foreigners. That was five months before he and I arrived; it will contain such information.

[Mitsuhide is almost getting exhausted, passing this information on, but he knows it is important to the rest of the Vatheonites.]

People leave at random, as far as I can tell. There have been patterns in arriving, however, though this was not always so.
