The following account was recorded in the agent's log during your transmission: Uh, massive chunks of Antarctic ice sheet are somehow embedded in a network of twisting, black lava tubes, their frozen surfaces reflecting the flicks of deep indigo light dancing across the cavernous space. The air's got a weird, expectant heaviness to it, like right before an avalanche, and it smells of damp earth and woodsmoke. A gleaming, polished obsidian disk... just seems to be embedded in the heart of a frozen chunk, and its surface is somehow reflecting an image of the Sirius star system that looks nothing like what we know it to be.
