Dwarf-y stuff about the Stone and Orlais and Leliana

I've always been intrigued by the Nexus Golem you find in that cave on the Sundermount in DA2. Not only does it have some phenomenally expensive wares (and creepy ones, IIRC – I think it’s the shop where you can get the Belt of Elven Hair. Yuck.), it says some pretty cryptic things: 

I don't know if anybody elsewhere in the series says "The Stone lives beneath Orlais" – I have a vague notion of Caridin saying it, but I may be misremembering – but I did find something interesting about these phrases in The World of Thedas, Vol. 2 – in Leliana's section, of all places.
