Sanctum of the Twelve an Amdapori structure?

This sky-scraping ivory cathedral was build following the Age of Endless Frost—a dark period in which the realm was overrun with famine and disease—to serve as a place of refuge and respite for all who sought succor. Soon after, however, it fell into ruin and was all but forgotten...until the advent of the Seventh Umbral Era saw need for its rise once again.

The architecture for both are VERY similar. Stone masonry with arcs and tall spires with ridges.

Based on the sight-seeing log the Sanctum predated the Amdapori since it was created in the 5th Umbral Era, while Amdapor civilization was in the 5th astral era. So at the very least this is a proto-Amdapori structure. Note also the fact that this was a place for succor and the Amdapori developed white magic specifically to provide succor.

Nice catch. It indeed looks Amdaporian. Though, the sightseeing description quoted says "following the Age of Endless Frost", hinting more toward 5th Astral, so I'd say that lines up perfectly with other Amdaporian constructs.
