Kaspar Hauser

 was the primary product of House Arpexia's jungle children project.

He was planted as an infant onto Earth at Nuremberg in 1823. Within three weeks of socialisation into human culture, he was able to read, count, write, and play a harpsichord. However, all of these accomplishments considered trivial by Homeworld analysists, who could achieve the same proficiency with an hour of high-intensity neural training.

Overall, Kaspar Hauser was unaffected by his time spent on Earth. However, as an inexplicable element, he left a large effect on local human culture: in response to his presence, Germany split into hostile parties, with many claiming that he was the Crown Prince of Baden.

In 1833, the project was deemed a failure and he was excised from the local timeline with a dagger wound. His name later inspired the Hauserkinder, despite that, as a jungle child, he represented something completely different. (PROSE: The Book of the War)
