While adventuring in the Commonlands I came across a peculiar key. Judging by the poor craftsmanship of this key, I'm willing to bet that it is of Goblin make. The number of teeth on the key also tells me that the lock this goes to is more than likely a Freeport sewer grate, as the tumblers in most Freeportian grates require only a few, but rather large teeth to open.
