I thought that might get your attention and carry a little more intrigue than, "hello". Sorry about what happened to Jon Snow, btw. I have not read the books, but I think the "red woman" might bring him back. At least, I hope so. It's already been done twice (that I know of), so the precedent is there. I think there's hope for Mr. Snow. Besides, if he's brought back, wouldn't he be free of his oath to the nights' watch? His watch was, after all, abrubtly ended.
Let me tell you about the name, byfrexia. In the 1980's, Marvel Comics launched a series of graphic novels in a monthly magazine called, Epic Illustrated. One of titles that got some early traction was called, The Metamorphosis Oddyssey. The main character was Vanth Dreadstar. He would later get his own mag. Dreadstar's homeworld is a frozen planet, called Byfrexia. And, there you go.
Jim Starlin was the writer/creator.
