This is something I've been curious about for a while now. The Sword Logic is a concept that encompasses all of the Destiny universe, especially the servants of the Darkness. It's essentially 'kill or be killed' tied to 'to the victor go the spoils.' It's not an especially evil system. But it is inherently bonded with the feral nature of the universe. So here's where my question comes in. Nokris, as explained in Warmind, was cast out due to his defiance of the Sword Logic through necromancy. A necromancer is a person who practices necromancy, a form of magic traditionally related to revival of the dead. This is heresy against the Sword Logic because death is its furnace. If the dead do not stay dead, the victor has neither killed nor gained the spoils of the loser. They have no right to their power and the Sword Logic will reflect this, potentially with a drain of power. So, based on this, I don't think that Guardians can ever fully benefit from the Sword Logic. Sure, we killed Oryx. But notice we didn't gain a significant amount of power from it, nor do we lose it when we die. We got a weapon that we fashioned from his parts, retaining a fragment of his power, but it never really becomes ours, does it? Especially since it's 'destroyed' like any other weapon at the beginning of D2. Now, potentially, could a Guardian devote themselves to the Sword Logic? Sure. But they would have to eschew the power that was given to them without killing (the Light) and their means of reversing death (Ghosts.) Sounds... kind of familiar. Wait, Dredgen Yor...
