This was a concept stemming from the age old question of "What is your perfect monstergirl?" that resulted in the creation of this character/race.
[Lore]
Light Dragons, not to be confused with white dragons, are exceptional cases within the normally neutral races of dragons that have chosen to side with the light & dedicate themselves to the protection & preservation of the mortal world.
At least one of these beings has been subjected to the Satyrization process as all inhabitants of the inverse tower had been millennia ago.
So far as is known she may very well be the only one of her kind & one of the very few benevolent dwellers of the tower.
As of yet she has only been encountered thrice & was dubbed by the legendary hero himself with the moniker of Andelle.
She is known to assist promising heroes that have made way to the deeper levels of the tower but will only approach those that are pure of heart.
This is because of her nature as a light aligned being but also out of fear of falling to the side effects of the Satyrization process should she encounter one that might pine for her.
