Welcome. I will keep the heads of your family to decorate my armour... is that too morbid? Too much Chaos style. I'll stick with Tyranid body parts, but I'll still slay Eldar if they would only stop skulking.
It's not our fault that we interfere with your plans regularly because your foresight cannot predict our stupidity! Also, welcome to the forums foul xeno walker!
Xeno!!!! Welcome. May you be more than half as strong as you come off if we must stand together. If you ever must stand against us Blood Angels and our Emperor... than may you accept Eternal Peace, with honor.
Hail and well met, kinsman. But accept a word of advice from me, and do not place in your trust in these Astartes - gorillas the Mon'Keigh apes have bred to protect themselves from a galaxy that is all too terrifying for their tiny, insignificant existences.
We are few, and if they shall join us against Chaos and the Silver Demons, i'll gladly fight at their side. If they stand in our way, they shall be utterly crushed.
I suppose you may be right in this. Besides, even if - WHEN - the thought of betrayal crosses their simple minds, what can they do to us? We will have seen it, and a thousand other possibilities far before the thought enters their head. Seeing them beat their chests after they realise they're striking at ghosts and illusions is oh-so-amusing.
