I can't sleep so I will go ahead and cast my vote..... So, after the battle of installation 00 all beings are set free from that horribly bondage in spirit and dignity set on us by the sanshyuum, then, we all get sucked back into that and the only other option is o.n.i???? NO!!!!! WE are better then that!!!! I am better then that!!! No more! Then everything we where set free from will be in vain! You want a covenant? hear is a covenant for you. I am willing to offer freedom, protection, life, and love, in return all I ask is loyalty, and to be no more treated as a outcast among the galaxy. What are you willing to give for your freedom?? is loyalty not a reasonable price?
one word, SPARTANs, why choose something in the covenant if they get their butts handed to them by (as I was once called on my tour of duty on Reach) the Section Three Freaks (this applies more so to the II's as I am a III)
but if i had to choose one, it would totally be Sanghelli, I met a few on my tour of duty on Sanghellios, and these guys oddly did not want to rip out my throat (but told me to get out once i mention that I killed their brother and ate him, not even reciting some akward death poem).
