You misunderstand, this is Tau space, despite what the Gue'la may claim, and you are welcomed to it as friend. We too have suffered difficulty with the Or'es'la, since it seems they wish no unity. We would be honoured to have you fight alongside us against this common enemy. You will find it to the benefit of both our peoples. You will find it, I have no doubt, to be for the greater good.

BTW, I finished reading the new demons codex and it struck me that it was written with the 5th ed rulebook in mind. It references one of the new universal special rules and talks about grenades as offensive and defensive, the way the leaked rulebook does.
I have the daemons codex but have been lazy was this refering to all grenades having ofeensive/defensive use or is it talking about current offensive/defensive grenades (as some grenades are of course are used when you get charged.)
