I've been going through the data that Glitter Edifice sent me. It mentions sites in Aridia, prospected but not thoroughly explored. Mishi is perhaps the most famous system in that region, but one must not forget that the region is also connected to the Blood Raider realm of Delve.
The Blood Raiders (evil in its purest form) are in a way the successors to the Takmahl empire. They loot and raid the Takmahl temples. That became very clear to me during the expedition to the labyrinth, as our valiant LUMEN fleet found them crawling all over the holy rock of the Takmahl, at the center of the labyrinth.
This proves that the Blood Raiders haul treasure from the old Takmahl systems to their hideouts in Delve now, and to staging posts in Aridia before that. Aridia is the gateway region from the Amarr Empire into Delve!
My working theory now is that first, the fleeing Sani Sabik took a large number of holy relics with them, and created the Takmahl Empire. After that collapsed, the Blood Raiders took the artifacts from the Takmahl with them - including our ancient relics, and stowed them in their hideouts in Aridia. Some made it to Delve, but I reckon many remained buried in "treasure islands", never retrieved as the pirate raiders were killed by our Navy before they could retrieve their buried loot.
