Crota's End Grimoire / Spoilers (Destiny)
From the Crota's End Grimoire card:
"Toland tells us that Crota's presence in our world is a shadow. That its true power resides in a netherworld forged by his will. We must pass through a keyhole between realities, navigate the seething midnight of Crota's world-mind, and overthrow the ascendant champions that gather to his throne.
Toland speaks--he hardly seems mad, at times--of the terrible things that await us. A secret song he hungers to learn, and the issue of that song, an ashen burning star-husk that looms above, the utter antithesis of life. He talks of it with a curious ambition I do not want to understand."
Just in case anyone else was wondering where the heck we were during the Raid.
From the Crota, Son of Oryx Grimoire Card:
He hides in the dark below: the monster of Luna, the titanic god-Knight who walked the regolith beneath a sky of green fire and butchered the greatest army of Guardians ever assembled. We abandoned the Moon rather than face him.
Whispered lore and fragmentary theories suggest that Crota represents a distinct class of Hive entities, not resident in our material world. My latest synthesis of this scattered esoterica suggests that Crota's 'home' is a universe created or remade by his power and occupied by Hive organisms of immense age. Any Guardian formidable enough to return with information on this dark reality might help us understand the Hive's goals for our own world—and, more pressingly, such an expedition might provide the key to Crota's defeat.
The epithet Son of Oryx is an ambiguous translation, often disputed. At this time, no direct action by Hive entities of more expansive power has ever been observed. Those who trade in Hive lore bicker over the exact positioning of Crota—is his world the apex of Hive power, or is it the youngest and most accessible of a string of netherworlds, each host to a more terrible Hive archentity?
Concluding with a fun comment:
The nature and possible interrelationship of the Vex gate system with Hive netherworlds remains unexplored.
Next patch Crota will teleport 3 random Guardians instead of none.
