This is my first scenario so please let me know if there are any balancing issues/bugs/incompatibilities.
There were fifty people from the New Andrestan Alternative High School on a glitterworld that signed up for the trip of a lifetime--visiting one of the planets on the forefront of construction and terraforming. Something went wrong on the way, letting your ship coast all across the galaxy over the span of years and years with nobody knowing. While the cryptosleep caskets automatically opened up moments before reentry only ten people made it to the escape pods in time. There are no guns in the pod, you find. Not surprising for a school trip, hmm? Or are there? Thanks, Russ the security guy.
Your faction will be a New Arrivals.
Start with 10 people, chosen from 10.
Your people will be at most 19 years old.
Arrive in drop pods.
There is more information about the start parameters, but is hidden for surprise/tension.
Semi-difficult without Cassandra; quite difficult with Cassandra. All of your pawns come from, as described, a glitterworld, so they have some perks they otherwise wouldn't. They're also a bunch of volatile high schoolers in a tense situation with a crashed ship holding experimental and dangerous tech causing environmental side effects, so it sort of balances out.
