There are two weird-looking statues in the west of Caledon Forest, which you can reach with your skyscale (see: https://imgur.com/ioDCmv4 )
Any idea what these might be? Can't seem to pinpoint any lore, but they sort of remind me of Jotun, for some reason? Seems to be corresponding to the GW1 Riverside province (but it's not the Temple of the Unseen).
Edit: Double checked this, it's north of Riverside, probably on the south-western edge of Twin Serpent Lakes
