The following account was recorded in the agent's log during your transmission: Faintly luminescent jellyfish drift within a frozen, crystalline cave beneath a glacier. Umm, the air pressure feels crushing, and I can smell the faint tang of ozone mixed with the sweetness of burnt lavender. Shafts of dim light filter through the translucent ice, illuminating etchings that resemble alchemical symbols from the Libellus de Tinctura - they're pulsing in sync with the hum I previously heard. The cave seems to be reflecting a distorted image of a pulsar from a distant star system, even though we're deep beneath the ice.
