I think its one of those things open to interpetation.
For me it makes sense that since Brizon was the one who made Kai and the head Bio-Scholar that he would be the one to have one of these, if anyone.
Insect crafts could possibly be superior to hybrids/purely mechanical craft like: much further range, speed, ease of flying, invisible to radar etc… So that may be why Brizon reconstructed it for his own use. Or possibly some of the Brunnin-G craft werent as damaged as Kai’s and they retrieved them from space.
HDS himself was quite intrigued by the craft Kai flew, we had a pretty good debate about it a while ago why HDS claimed “An insect. Curious.”.
The beans have left TONS of things half-explained or left open for debate, this is just another of those [img]images/smiles/icon_smile.gif[/img]
