Bersyrim relics and conjectures

I've continued to investigate the nature of the artefacts I recovered in Bersyrim. I think they were not collected over the years there from all sorts of other places. They are too consistently from a single time period, and in a singular style to be a hotchpotch mix you usually find in capsuleer's cargo holds or adventurer's collections. 

So, I hypothesize there was an expedition or a colonization attempt from the Takmahl at some time. The stuff they brought with them would be representative of a particular era and maybe particular style. The problem with this is that there is no known colony, nor did anyone find a colony ship wreck or exploration vessel wreck here. 

The other mystery is why they would choose such a place, far from their homelands. Maybe the even bigger mystery is how they got here! It is out of reach for their ships unless they would travel for decades. So, this leads me to another conjecture: Talocan wormhole technology. 

The Talocan, a much older and more advanced civilization than the Takmahl, possessed ways to open up wormholes. It is well known and document that the Takmahl found Talocan technology and reverse engineered it. So why not experimental wormhole tech?
