Irrai is amicable enough, if cryptic. It was hours before she seemed to comprehend any language but old Ayleid and Daedric pidgin. When she finally spoke, she did so with eloquence and a surprisingly cheerful curiosity. According to Irrai, she once served Culanwe. She claims the seal upon Laeloria was placed by Azura herself. While I'm apprehensive about trusting any Daedra, Winged Twilights such as Irrai are known to be servants of Azura. Beyond this, the shrine outside Laeloria is proof enough of this location's importance to the Daedric Prince of Dawn and Dusk.
