Goddess Ilias

A central figure in the mythos of Monster Girl Quest and a religious figure in the game, Ilias was said to have cast down the first Monster Lord. She is depicted as an angelic being and appears to Luca in his dreams quite regularly to guide him in his quest.

As she wishes to destroy all monsters, she uses Heroes to go on quests to destroy the current Monster Lord and defeat any monsters on their way. In return for their "unwavering service" she gives them her blessing at a coming of age ritual. The blessing itself protects the Hero by making their semen repulsive to monsters, apparently tasting like angel liver.

Though this makes them safe from the more erotic attacks from monsters, they may still be put at greater risk from normal attacks and devouring as they can't offer use as a source of food.

Ilias' religion spreads far and wide across the world, apart to areas such as the isolated land of Yamatai and the obviously the Monster Lords' home in the Northern continent. Adversely, her following is a lot stronger in the South, which is where her temple is based and the player starts. The central continent is a large grey area with differing attitudes to monsters and her teachings in each village, but generally the more North you go the less the teachings are followed.

Should the player lose, Ilias will appear to give them guidance on how to defeat an enemy, though her descriptions can sometimes be vague. Should the player ask for her guidance 50 times, she will become annoyed and disgrace Luka which adds her to the Monsterpedia as an entry.

Also, as the game continues she will grow increasingly weary, breaking the fourth wall as if she was aware of the many, many losses the player may go through. Her comments begin to regard Luka as a pervert, foodstuff and a slave to the monsters he encounters.

By the end of Chapter 2, Ilias is revealed to be the main antagonist of the game, wishing to destroy humanity and monsters both.

Trivia:
In Yamatai one of the villagers suggests starting up a shrine for the Godess Ill-Ass, a pun on the mispronounciation of her name as the locals are unfamiliar with the religion. Luka thinks she would not approve.

A good number of areas in the game have their own, more leanient, take on Ilias' teachings, Sabasa's royal family has a history with monster blood while Port Natalia is more accepting with resident mermaids and the women of Grand Noah just like to see men get raped by the resident monsters in the Colloseum.
