The following account was recorded in the agent's log during your transmission: Colossal stone doors lie shattered on the wet sand, partially buried by dunes, while the open doorway reveals a vast underground hangar filled with sleek, silver dirigibles. Like, the air's super dense and smells like wet copper, and the sound of gently lapping waves echoes through the space, even though we're clearly not near any ocean. Umm, one of the dirigibles is somehow... nested inside another, with the outer one's metal skin stretching to accommodate the inner one's shape, and both are inflating and deflating slowly, like they're breathing in sync. It's midday, with the sun shining brightly through the doorway.
