I'm a very new GM, and am starting a campaign with 2 PCs. They just threw me a curve ball last night and I'm not sure what to do. They created characters, gave them good backstories, personalities, etc. However, when we came to the point of "How do you know each other?", we couldn't figure it out. I basically got told "That's for you as the GM to figure out". No hostility, they are just leaving it up to me. The first character is a monk like human living out his life on a standard civilized world. The other is a Zabrak that has been exiled from his community and ends up on the same world. I was planning to start "Lessons from the past" from the core rulebook, but it doesn't make sense in the existing context. Do I,
1. Create a simple couple of paragraphs explaining that "You meet and become friends and several months later..." and then start the adventure I had all prepared? Obviously I would add some backstory detail, but it all happens offstage.
2. Create a simple adventure where they meet? Perhaps the Zabrak stole a ship or is on the run and meets up with the human who helps him? Other ideas? If I do this, how far do I go? At some point I feel like I need to go "And several months later...", but I'd love some advice. This sounds like the "cooler" idea, but I'm not sure how to do it well and I'm afraid it would bog down quickly.
Thoughts?
