Update: My post was so wrong...

I figured it out when I saw [url=http://roosterteeth.com/archive/?id=8939]this Rooster-Teeth trailer[/url]

[url=http://en.wikipedia.org/wiki/Pyrrhic_victory]A victory that is one step forwards, and two steps back[/url].
"So you may prepare your guardians, but take heed: there is no victory in strength."

Why did Pyrrha stop competeing, and join the school? She was winning, right?
That'd be like Master-Chief joining a military-academy, not as a professor of ass-kicking, but as a student.

So the good news is that Pyrrha is NOT based on Achillies, and probably won't die.
-I'll let you infer the bad-news for yourselves.

BTW: Roland is the name of a certain Paladin whose death is pretty well paradied in Lord of the Rings.
