Wandering Inn thoughts: Who are the Goblins and what do they seek?

I am in book 4 Winter Solstice of my re-listen; 3.29 G

No one remembered who the Goblins had once been.

Every time i come across this line, i wonder what pirate has had in mind when writing this. And if I will ever fine out? Probably it's related to how the last goblin king turned from kind to raging.

This chapter also sees a mention of the key that Garin and Tremborag are looking for and which apparently is somewhere far worse than "in the heart of Invrisil, behind one of the Walled Cities, or at the bottom of the sea". We do know by now that it is somewhere in the High Passes. Surely that means it is in the dragon's hoard?! Must be...

I bet pirate will make us wait for that reveal. And then we will suddenly all realise that now we still only have two keys and no idea what they open and why there are two of them :D
