Gloriana and the Skull Architect had a lot in common from a professional standpoint.
They were second-class mech designers. They both pursued material perfection in mech design.
Of course, there were slight differences. Gloriana pursued the perfect vessel. This caused her to develop a much stronger focus towards individually-customized mechs. She did not want to make any compromises at all into achieving the greatest fit between her mechs and her clients. This meant that she wasn't able to design mass market mechs by herself.
From what Ves knew of the Skull Architect's work, the former Fridayman nominally specialized in energy transmission. What this actually meant was that the Senior actually obsessed over achieving the maximum possible efficiency.
While the professor made steady gains in this field, eventually he approached the limits of what was possible with his abilities.
