The Snowflake Ship is a mysterious abandoned ship that rests in the clouds of Neptune. It was used by Prince Oberon and his colonisers as they left the Solar System. It is unknown why the ship was left as a relic around Neptune.
The ship is made entirely of processed magic - not orichalcum, vril or aether but energy magic. To those that can sense magic, they can sense that it is Earth magic and incredibly ancient. To get inside, a person would need to magically phase into it[Pan 2].
