While searching, he is dismayed how poorly his Levnises were treated and reveals he has an injury, and that his gauntlet was made by his masterpon as a token of recovery. After getting the necessary part, the party returns to Elise's Sprout. There he builds a non-combat Levnis named Mechafriend. However the celebration was short-lived with the arrival of Consul Q, forcing him to return to Colony 30 to finish building a very powerful Levnis, however in reality Valdi wants to destroy it.

However Mechafriends and the party arrives to protect Valdi from harm.
