Custodes Ignis Sancti, or Keepers of the Sacred Fire, the Blue Eyed Angels. In all, or at least most of, their glory.
EDIT: A little commentary, now that I can spare the time:
Basic metal lord, I did a head swap, and added an older raptor backpack.
A daemon prince, made from a Inquisitor scale navigator model. Plasticard for wings.
Old dark angel whatnot, turned into my Sorcerer Lord.
Tzeentchian Terminator Lord with Scrolls of Magnus! Uuu!
(A very old convertion, lucky me.)
Converted plague marines. Or at least some of them are converted.
And my Khornate Terminators
Bunch of tacticals and havoc. Huh, I really went nuts there.
Khornate Rhinos, yay for the return of destroyer blades!
Some Rhino detail
And the 'zerkers who ride them rhinos.
Tzeentchian rhino, for some reason.
My dreadI mean Hellbrutes. Damn. Anyway, other from FW, other a conversion from the loyalist dred.
And my beloved defiler with a unphotoshopped pic with the paper edges still showing.
