The Jist
Aeternia is a real time 3D adventure RPG with shota main characters and MiLF female characters. Sex with the female characters is built into the game play of the game, but it is possible to play the game just for the sex and not any of the adventuring.
The Story
Aeternia is a forest in another plane of existence discovered by explorers from the Fei Kingdom of Avalon. The Fei are searching for treasure, culture, and Soul Shards. Aeternia has been discovered to be abundant in all 3, but the forest is cursed. Monsters creep from the trees at night making permanent encampment very difficult. To repel them the Fei have created Gild Dust which will create a temporary shield these monsters cannot penetrate. Another problem with the curse is the soul Shards found in Aeternia are corrupted and cannot be used by the Fei to grow stronger. Luckily a solution has already been discovered. Ritual sex with human woman purifies the Soul Shards and allows the Fei to use them to enhance his abilities. to this end the Kingdom of Avalon has invited women from the human world to come to Aeternia for adventure and profit. The little detail that they're there for sex is conveniently left out.
