A LONG TIME AGO, IN A GALAXY FAR, FAR AWAY...
I'm not too familiar with Legacy Era, so a lot of canon will go out the window. Please try and keep things at least related to established Star Wars lore though. I won't be too picky though.
After the fall of the First Order, there was a power struggle. A war to fill the power vacuum that was left behind when the First Order collapsed. Various factions are vying for power. Some good, some bad.
A new Sith Order has been discovered on Korriban.
A new Jedi Order has formed.
Remains of most older factions have strongholds around, but are no where near their former glory.
Feel free to make your own Faction.
In an attempt to become the best faction, nearly every faction has been sending parties into the Unknown Regions. In an attempt to find some weapon that could turn the tide.
Now, since literally anything could be in the unknown regions, I will allow nearly anything. You could have characters from the unknown regions, or technology that was stolen on a previous mission.
So, how does this tie in with you, as the Players?
Well, you will play members of the various Factions sent into the Unknown regions. Intel has come in about a mysterious weapon that could tip the tides of war. Give whoever has it, the utmost advantage. Your characters can be all from the same faction, or from different ones. The idea is that all the different factions sent a ship to this planet. Then, they get attacked. The weapon wasn't really a weapon, but a trap. A huge EMP (or something similar), wipes out most of ships, and causes them to crash. Now, cut off from the rest of the war, the survivors are meant to work together to survive, and get back to known space before they are killed by something big.
If you wish to join, use the same character sheet as my character which will be up in a bit.
