Overruled, Jovik shrugs and steps back to watch. Danth joins him, his weapon at the ready. Jokad stands beside Kibb, the great bear seemingly calmed by the presence of the big man alongside him, but its eyes stare unendingly at the door and Kael, as if hoping, waiting...
Kael points his finger towards each nail in turn, an inch from the metal head, and sends his acid into each one. The nails hiss and melt away, leaving small rivulets of dull grey metal dripping off the wood and onto the floor. As Kael works, the rest of you can see a pile of discarded wooden beams with bent nails off to one side, as if the ogre-kin have had to lever off the bars several times in the past, and haven't always been patient enough to try and reapply the same beams. It would appear the prisoners have not been left entirely alone in this area the whole time they have been captive.
With the last nail melted, Kael steps back to survey his work, and then tries one of the planks. It lifts away easily in his hands, stuck only lightly by the melted metal to the door behind. One by one he lifts the planks free, revealing a large door with numerous nail holes marring its surface.
There is no lock, probably explaining why the door had been nailed shut, just a large handle.
