Though Ves had 'discovered' hundreds of odd applications of luminar technology, the crystals he made with the help of the crystal cube still failed in one aspect.
They broke too easily.
The MTA must have figured out a way to synthesize harder crystals that were at least comparable to other second-class materials, but Ves didn't have access to that know-how.
He felt tempted to contact Master Willix in order to beg her to grant him access to this crucial research, but he had a very strong hunch that he would return empty-handed.
She rejected his request before and had little reason to think it would be any different this time.
In general, the MTA did not like it when humans dabbled with alien tech.
It was one thing to develop technology derived from alien theories and applications.
It was another thing to directly make use of alien technology without understanding their fundamental mechanisms!
