The cold wasn't too harsh through all his layers, but the sudden onset of it had Saralegui drawing a deep breath, and the thinness of the air was all too noticeable, like trying to breathe high up on a mountain. With a shudder, he pulled his cloak around his and frowned deeply as Hiccup tried to do something -- open the bulkhead, probably, but it didn't seem to be working.

"Shouldn't this be what you're good for?" he snapped, sweetness vanished for the moment in his panic. And immediately he regretted wasting the breath on it, gasping shallowly with the air seeming even thinner than moment before. Leaving Hiccup with Toothless straining at one of the bulkheads, Saralegui ran ahead, picking out the doors in the dark and trying one after the other. All were thick and heavy and without any mechanism he could figure out to open them.

One, however, looked different even as he approached it. Still nothing like a handle to open it with, but it looked less imposingly sturdy, and when he smacked at it it rang through the hall with the sort of hollow gonging of a thinner metal.

"Leave that! T-try this one!" he called back, hitting it again for emphasis.
