Sekhmet, daughter of Ra. The identity of the mysterious being behind Sanguis Pluvia had been revealed, which should not have been as simple as it was. If it were so simple, that one only needed to peer upon the eyes and recognise the familial traits the eyes bore, then there were many who should have recognised her long before Lex.
As a being of Dao, Sekhmet had naturally taken precautions to protect her identity from being discovered. Let alone recognizing her from her eyes, even if she stood in full view of everyone, no one should have been able to peer into her identity. This was further exacerbated by the fact that when the Innkeeper attacked Ra, all information about and related to him was wiped from existence, at least on lower levels. That meant very few beings in existence even recalled Ra's children - at least, they did not recall them as children of Ra.
