Welcome Brother! We hope to count you among our ranks. Glory Eternal awaits us. We might fall in battle but our names and deed shall never be forgotten, our actions shall light the way for the return of our beloved Emperor. Now, isn't this a far better greeting than : "Waaagh. We'be bushing yo headz you noob!" , or : "Welcome. Your body and soul belong to us, when you fail and die you essence shall either be devoured by hungry demons or susbumed into one of our merciless Gods. Have fun!" You could of course join the Eldar host. Nothing beats living like a wandering circus band! The choice is yours...
Okay now thats some heavily mutated subhuman from some oceanic world. Welcome to the forums! Based on your allegiance, I offer you a mug of mjod or the sharp edges of a lightning claw with equal excitement.
