Then Sam sees the first angel releasing his soul and transferring it into his partner. Then, as the first angel falls, the voice says, "Now that you have given your life to him, he shall live his life and find a new partner, and you shall live eternally. For giving up your life, I can grant you one wish." 


The first angel says, "Can you give the angels a blessing to be eternal partners, such that no one can separate them?" 


Then Sam sees Amber Mount being created. The voice says, "From now on, Amber Mount will be the angel's sacred land, where two angels who are chosen by destiny shall come to offer the ritual and get blessed. The one who's blessed her shall never part. I grant you one more decree; the ritual will be named after you." 


As the mirror disappears, Sam instantly says, "Eta Relin."
