Are there any biographical texts on them? Surely such an exalted person would leave a mark on history—besides his work, I mean. Or hers? I take it that the gender of the Sage is not known?
I also would like to learn more about the sacrifice the Crystal Saint made. There are so many collective pieces...the Voice of Song, the battle between Light and Dark Knight, the sacrifice of the Crystal Saint... I now wonder how all of these–perhaps more—threads wound together.
