And Sun had previously mentioned that during the City of Silver's first expedition, led by a Shepherd elder, into a semi-abandoned temple of the True Creator, they had discovered the name "Rose Redemption"...
"That Evil Spirit, according to Mr. Tower's speculation, should have formed from the amalgamation of the souls of three Angels...
