Oryx at 390 light — the challenge mode, the hardest version of Destiny's most demanding raid encounter, the Taken King in his throne world at maximum difficulty. Legends aren't born is the grind philosophy as pure as it gets: the light level, the build, the understanding of the encounter mechanics — none of it was given, all of it was earned through every failure that preceded the success. Respawning is the mechanism. The respawning is the whole game.
