Miss Alexa Streon came from a Terran ancient clan. She was familiar with the benefits and the rationale of building up a mech roster of exclusive models.
However, the Larkinson Clan was different from the Streon Ancient Clan.
The latter was a behemoth and had so many mech designers at its disposal that it was not short on exclusive and commercial works.
The Larkinson Clan was much smaller and needed to earn a lot more money in order to deepen its foundation.
The Larkinsons had a lot of ambitions, but not enough funding, resources, access and relationships to strengthen and deepen their roots in human society.
The successful expeditions occasionally produced massive windfalls, but these were incidental and unreliable earnings that had nothing to do with normal economic activity.
