Jimi turns and glances over his shoulder when he hears Midgrim mention the key.
"A key? Good job, Midgrim. Was it left here by those Kobolds, or is it of Dwarven make? Might give us some clue as to what it will unlock... and if it's hidden here, does it make sense to think that whatever lock this fits might not be far away...?"
Feeling relatively sure for the moment that nothing is approaching them from behind, Jimi moves to take a look down the corridor to the east, that they have not yet explored. He glances down the passageway trying to see what lies ahead.
