Need help finding...

[RigaMortus2]

that prestige class that was on the WotC site which used the Phantom Steed spell... I forget what it was called. Anyone know? Anyone have the link to it?

I believe that would be the Phantom Knight from the Five Nations book.

Edit: Sorry, the Knight Phantom.
It's also on the WotC site.
