The headaches have almost disappeared. Score another round to my esper instructors.
They kept telling me that my headaches were analogous to sore muscles when I tried something new physically. Well, they were right. Over the last few fivedays I have seen more parts of this continent than I have over the past two years, and while my head felt as if it was going to explode the first few days, I can now go almost anywhere I have seen and levitate to a height which is uncomfortably cold with no headache at all. And once I am high enough, I can pick out landmarks and teleport to them with little effort.
It is a large continent that I have landed on. To the north, trees and watercourses become steadily more frequent until finally I find myself in jungle. By the sun, this jungle continues past the equator, bordered to the north by more savannah and eventually by true desert, drier than anything near my shelter. Farther yet, I came to a great salt sea.
