Ves and Beatrice did not achieve a lot of progress on developing the Superdimensional Regalia.
They became hampered by their lack of understanding of superdimensional matter.
It did not help that they chose to work on the most difficult weapon-grade superdimensional matter either. Its properties were exceptional, but that amplified the difficulty of trying to transform it into a more usable form.
They needed to gain new understanding, insights, instruments and experience. Many other people had fallen into the same boat. Those that managed to walk ahead of the rest jealously guarded their exclusive secrets in order to maintain a competitive edge.
Ves felt frustrated by that kind of behavior even though he would have done the exact same thing if he was in their place.
Superdimensional tech had become the new technological frontier of both humans and aliens.
Nobody wanted to spread their secrets easily, especially to the other side.
