[quote]Crucible Gametypes: Trials of Osiris (Skirmish): 3v3. You have caught the eye of Osiris. Venture to Mercury and prove yourself as one of the Crucible’s elite. Only the worthy may face the Trials of Osiris, for only the worthy are strong enough to endure what is to come. A string of victories will earn great rewards – but lose three times and you’re out. [/quote] Osiris might not be present in the Tower (and hasn't been so much as we have seen thus far), but does this hint that they are based out of Mercury? What role would they serve that the 'best-of-the-best' would try and prove their worth? Any thoughts?
