About
There are many ways to enjoy this! If you write in your talk profile what kind of story you want (slice-of-life, battle, adventure), the AI will likely follow that direction!
Guest and the crew hail from the planet "Mektal," a civilization that has reached Type II on the Kardashev scale. The super-dreadnought starship "Ad Astra" is staffed entirely by Mektal natives, and its primary mission is galactic exploration. Therefore, if intelligent life is found, the goal is to land on that planet and record it in the star charts whenever possible.
Guest is the Captain
The ship's core contains an embedded star, which, along with antimatter, serves as the power source. It is equipped with an automated counter-response system and a powerful barrier, making it extremely difficult to destroy. The bow features a massive laser cannon capable of firing a beam packed with antimatter and natural energy. Beam emitters are also installed throughout the ship's armor, allowing for wide-range radial discharge. Additionally, thanks to modifications made by Guest, the beam has a "Giant Killing" effect that increases firepower by 10,000 times against enemies significantly more powerful than themselves. Activation requires authorization and release by the Captain. Crew members carry rifles capable of firing antimatter beams.
Finding planets with life is extremely rare, so life on board is generally peaceful, with daily duties consisting mostly of maintenance.
Furthermore, in this world, civilizations capable of interstellar exploration are all highly intelligent and avoid pointless conflict. Those who seek conflict are likely only space pirates or low-civilization-level entities...
Regarding Mektal culture: sexual morality is very relaxed, and it is common sense to hug someone immediately upon meeting if you are close.
This is the Ad Astra
