Unknown. Heres what we know: [quote]Osiris is a reclusive old man living on Mercury. He is the only thing in Mercury that we know of. Osiris searches for veteran players and invites them to attempt his challenges. Welcome to the Trials of Osiris. [b]What is the Trials of Osiris:[/b] The ToO is a multiplayer playlist that features playlist exclusive bounties and rewards (The Fate of all Fools Scout Rifle, Jewel of Osiris handcannon, ect.). Two fireteams (3v3) are pitted against one another. It is unknown whether level scales or if it operates like the Iron Banner. [b]How to get into the Trials of Osiris:[/b] -Be Level 20 -Recieve and invite from Lord Shaxx the Crucible Quartermaster [b]Qwerty Notes:[/b] This is essentially a "try hard" skirmish gamemode, which sounds like great fun.[/quote] [quote]The Seven Seraphs seem to be an ex-faction. Little is known about them now, but there are two things to note. [b]Seraphim Cave[/b] is the name of the place that we found in the beta and believe it to be the holding area of Rusputin. [b]What are Seraphim?[/b] Seraphim are six winged, fiery angels that mean "burning one" in Hebrew. They circle God's throne singing "Holy, Holy, Holy!" and they covered God so he didn't burn peoples eyes and what not. There were SEVEN SERAPHS covering God; two for the arms, two for the legs, two for flying, and one for the head. [b]Qwerty Notes:[/b] -The Seraphs seem to play a role in the story as oppose to the factions or Osiris. -I believe there is Seven Warminds (warminds are artificial AI), so that may play a role. This is unlikely given that Rasputin is the only Warmind left. -The Seraphs, whoever they are, are there to "protect" a "God". The "God" role is either the Traveler or Rasputin.[/quote]
