You're standing right next to the Pirate's Lair on this image, yes.
Ancient Gears can be traded to the artificer for something cool ;)
Ehh i get last two items too late... Be cool if you make some post update as in the light keeper! (as i remember, some items added later and i replay two or thee times...)
