Everything Starts Aboard The Advenna Avis

It's 1711 aboard the Advena Avis ship and a group of alchemists lead by Maiza is about to attempt summoning a demon to grant them the Immortal elixir. The summoning was proven to be a success and the demon granted them all the elixir, with 3 rules to go along with the elixir. Because they all follow Maiza's decision not to share the knowledge with those outside the group, it isn't long before someone gets greedy for the knowledge and that person is Szilard.
