+# People
+
+There are relatively few people in the game due to Jupiter's rings not being
+extensively settled.  The rings are more of a niche thing for adventurers and
+visionaries at the time of the game.
+
+Those few people should have maximally fleshed out conversations though, making
+the player happy to see a friendly face when they do appear.
+
+Each character should have an interesting, unique personality that sets them
+apart from the other characters. Let's outline the personalities/backstories:
+
+[THIS IS JUST BRAINSTORMING FOR NOW, ONLY PARTLY IMPLEMENTED IN THE GAME]
+
+1. Icarus @ starting area:
+    - "Tutorial character"
+    - Very chill, nonchalant
+    - Goes out of its way to help you
+    - Touristy, sightseer
+    - Very absorbed by his VR headset
+    - Grew up on a space ship where VR was the best way to see interesting things
+    - Travels the solar system to find beauty
+    - Not interested in creating anything
+    - Rides a Cruiser
+2. Nox @ pizzeria:
+    - Wholesome, easy-going
+    - Wanted to get away from civilization to have some peace and quiet
+    - Built a pizzeria into an asteroid
+    - Doesn't seem to care that so few people visit his restaurant, just keeps doing his thing
+    - Fascinated with the old times of the 1980s, he called his pizzeria "Old Earth Pizza"
+    - Wants to take care of people and impress people with his hospitality
+    - Reliable, people in the area look up to him as sort of a "governor"/"sheriff"
+    - Biotech/brewery nerd, grows his own algae for the pizza ingredients
+3. ??? @ pizzeria:
+    - Thrill-seeker, racer
+    - Cheeky, teasing
+    - Frequent guest at the Pizzeria to refuel and rest
+    - Good for some small talk
+    - Nerd about engineering, propulsion, rocket science
+    - Rides a MeteorAceGT
+4. ??? @ pizzeria or workshop:
+    - Engineer
+    - ADHD
+    - Deploys communications infrastructure across the rings
+    - Just passing through
+    - Grew up on Earth, is way too excited about being in space
+    - Totally a furry
+    - Has big plans for this area, but not enough time to implement everything
+    - Nerd about high energy communications technology
+5. ??? @ workshop:
+    - Mechanic
+    - Operates a workshop to craft and mod space vehicles
+    - Nerd about space suits and vehicles
+6. Ash @ hideout:
+    - Monk master of a cult of Buddhist origins
+    - Uptight, self-disciplined, driven, wise
+    - Not very agreeable
+    - Operates a construction site for a meditation retreat in a hollowed-out asteroid
+    - Deep distrust of AIs, wants to construct the hideout by hand
+    - Not interested in small talk, but up for deep philosophical debates
+7. River @ hideout:
+    - Monk apprentice
+    - Open-minded
+    - Had everything in her life on one of the planets
+    - But ached for profoundness, desperate for a meaning of life
+    - Frustrated by the rigidity of Ash, she thinks she knows better how to run the place
+8. Rain @ hideout:
+    - Engineer, tinkerer
+    - Very shy, unsocial
+    - Helps the monks to construct the hideout
+    - Totally insecure about her job, since she has no formal education as architect, she's just winging it, but the monks will need a 100% functioning home to survive
+    - IT Security nerd
+    - Operates a synthwave radio station, piggybacking on the communications infrastructure
+
+Minor characters:
+
+- Yuni @ secret location:
+    - Easter egg character
+    - Meta, breaking the 3rd wall

+- Clippy @ various locations:
+    - AIs which could get personalities as well
