I'm having a bit of a problem myself right now with my RL campaign and its that I've got an awful case of writers block for making campaigns. I just did one I've been wanting to do and I just don't have the time to make a bigger dungeon for the party to handle right now.
I have an idea for a campaign to kill time, and I'll have time after, but its very lackluster.
The basis is this is my own custom world. The tieflings and gnomes hate eachother and are in a constant state of war. At this point, they're at war, but the other nations refuse to join in. A group of gnomes wearing animal masks are going around in the southern regions of the continent the party is on and slaughtering tieflings in holds as sort of a guerrilla warfare tactic (even though they aren't part of the army at all).
So a bunch of tieflings are hunting them down but tracked them north. One of my party members, dear old Tyson-Chan, is a gnome who has an animal mask they identify as one of them. However, she isn't one of the ones they're looking for, but they don't know that so they kidnap her and interrogate her, and the party has to go save the barbarian from a race she absolutely hates.
Sadly, this seems VERY lackluster for a 4th level encounter. I'm guessing a lot of stealth will be involved, but definatley a lot of combat towards the end.
The party consists of one under leveled half-elf paladin (still level 3 at the end of the next encounter), one level 4 werewolf high elf bard, one level 4 half-elf sorcerer, one level 4 barbarian gnome and one level 4 monk or a level 4 rogue (party decides).
Is this a good idea of a hastily made session? I haven't had much time to make campaigns as I had the last few weeks dedicated to schoolwork, work and rehab meetings
