Squire of Legends PrC

[Aximili]

OK, I was looking through the Complete Champion's art gallery, and this one caught my attention. (So, I'm judging the book by the cover, sue me.)
Could someone tell me what's this PrC about, both in RP and statistics?
(no need to be specifical, just a general idea is more than enough.)

From its name I would for once admit that this sounds like it would make more sense as a base class.

[Tengu]

Duskblade sounds like a PrC though.

And no, I don't know any details about Squire of Legends.

Anyone know anything about this yet?
