Spreading the Gospel
Spiritual fragments were valuable and very hard to obtain. To get Ylvaine's spiritual fragment, Ves not only had to steal a culturally-important relic, but also perform several dangerous spiritual techniques.
Ves did not relish repeating the experience every time he designed an Ylvainan mech or adapted his other mech designs to the local market.
He began to consider if he should turn Ylvaine's spiritual fragment into a communal design spirit. It would be great if it could encompass every mech his company sold in the Protectorate's mech market.
While his understanding of spirituality was too shallow to know the answer, he seriously entertained the notion. The convenience of sharing a single design spirit over multiple designs was too great for him to ignore.
Naturally, this didn't mean he decided to become lazy and reuse his old design spirits all the time. He merely wanted to apply this solution in cases where the costs outweighed the gains.
