Both the Crystal Lord Mark II Project and the Sanctuary Project risked losing direction because Ves had not begun to work on their spiritual properties.
While his assistants would still be able to complete the technical designs of the two mechs, the lack of glows and design spirits meant that none of his people were completely aligned to their projects.
Ves already noticed this because he often had to clean up after the messes the assistants left behind in the spiritual foundations of his mech designs.
Even if he taught them how to focus their minds and free their minds from distracting thoughts, their insufficient concentration and lack of awareness meant that they deposited plenty of pollution.
This was a persistent problem that Ves always had to address in person. No other mech designer was able to design as focused as him, because he could immediately perceive the consequences of his own sloppiness.
