Crota's End (Grimoire Card)

The monster's name is Crota. He killed my friends face to face, one by one, and he relished it. In the name of all those lost I devote myself to his utter destruction.
This is my confession. If I transgress in your eyes I ask for your forgiveness.
In our world Crota seemed invincible. Together Eris Morn and I worked the problem, but found no hope. So we sought forbidden knowledge—the exiled master of Hive arcana.
We found Toland.
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.
Tomorrow I will ask Agah, Mota and Tarlowe if they will go with us. If we fail, I leave this record for Guardians to come. Remember us.
