Demigods are the weakest form of quasi-deities:
Quasi-deities: A category of weaker divine beings who don't grant spells to mortal clerics, but could advance to lesser deity if they had enough worshipers. This category is divided into three main subcategories:
Titans: The offspring or creations of deities. Titans include the CR23 empyrean, the CR23 kraken, and the CR30 tarrasque.[2]
Demigods: The weakest of quasi-deities, the offspring of a deity and a mortal.
Vestiges: A dead deity who has lost all or nearly all of their worshipers.

The correct answer to which portal allows you to see Lorroakan is also "The Nightsong is the immortal child of a divine being" further reinforcing that she is a child of Selune.
When Devas die they vanish from the material plane and it takes several years for their soul to return. This is not consistent wih Aylin at all.
Characters like Minthara and Halsin are also not at all consistent with their background in terms of power level either. Minthara is a 250 year old matron of Lolth, and simply a 6th level paladain and Halsin, a 350 year old archdruid who is "one of the greatest healers in Faerûn" is a 7th level druid who can't even cast Greater Restoration.
