Kraken Mare

In the distant, far-flung future, humanity's pursuit of a vital energy source known as "Black Ether" has awakened monsters called Krakens, which lay dormant within black holes. These horrors brought humanity to the brink of extinction. A thousand years later, the Krakens are worshipped as gods by a church that exploits them to spread fear and control the remnants of humanity.

Brave smugglers known as scavengers defy the iron fist of the clergy, risking their lives to mine black ether in secret for profit. The crew of the space ship Pulsar, led by Captain Paze, is tasked with extracting black ether from an extremely dangerous black hole at the request of the Mars-based pirate group Red Sand.

Oriale, a church agent and skilled Atomancer, lurks amongst the crew, pretending to be the innocent cook "Eden." But when the Pulsar is discovered by a terrifying Abyssal Kraken, she must reveal herself in order to save the crew.
