Are there Oaths available for Chapters other than the ones presented in the core book? Even in First Founding the original 5 Chapters get additional Oaths and the other Primogenitor Chapter get nothing. Did I miss something?

Honour the Chapter has new oaths for Black Templars and Storm Wardens and The Outer Reach has more general oaths that can be used by everyone.

No ;ove for the Salamanders, White Scars, Iron Hands or Raven Guard. It's a GW tradition I'm not particularly fond of. First Founding gave me hope.

Anyone come up with any House Rules for Oaths? I searched but didn't turn up anything useful.
