After plaing Hexen 2, there appeared a desire to create the same artifact but by my way. You should find the artifact, put it on pedestal and watch secret door opening.
The artifact was created in 2012 and fine-tuned in 2015 year
Ornamented floor and pedestal were created in 2015 year
Pedestal for the artifact was proposed initially by idea of some artifact in pc game Hexen 2
