Ok, so I’m running a homebrew campaign in a caveman setting with my family. They’re currently at level 3, and about to be attacked by an army of kobolds. (Yes, for those wondering, this is the encounter I’m playtesting on the PbP)

However, with this current adventure, I only have enough material for 1-2 more sessions, if I’m really lucky, maybe more if it goes a certain way. 

Theyll finish the adventure at level 4. I need ideas for another adventure after that, and my creativity is failing me. Y’all got any suggestions?

Ok 'caveman' setting is super vague but thats good because you can do so many things with it. 

You can have a new star appear in the sky and the local druid has began trying to map it. The players could be asked to go and tell other druids in the area to come and help prepare a stone circle for it. (So many adventures along the way)

You could have them come into contact with an highly advanced civilisation (in comparison) people who navigate the sea and use forged weapons etc.

Or even very simply have dinosaurs come back to life from spaceships.

You can literally do whatever you want.

All interesting ideas. I’ve had a similar idea to the second one… but it’s still pretty vague. 

What do you mean by caveman setting? It sounds like dinosaurs would be perfect, along with dire animals, mammoths, sabre tooth cats and the like. You could use dragons but reflavor them as magical dinosaurs. The Kobolds could serve one of the dinodragons.

You could do an encounter where you make a large maze like jungle or rocky area that is full of dinosaurs and they have to navigate it and find a way out. There could be velociraptor packs that they have to avoid, there could be neutral stegosauruses and triceratops that could be provoked if the party does not carefully find a way to get past them, and there could be a larger beast that is hunting them down because they angered it. 

You could introduce a tribe of dinosaur-like lizardfolk who they could trade with, or they might be captured by them.

Tortles would also make sense in a prehistoric setting.

A clan of sabre tooth leonin might be seen.

Have them fight a weredinosaur and be infected with a prehistoric form of lycanthropy. 

All interesting ideas! Thank you. 

Probably your main conflict in a "caveman" setting is person vs. environment... Include a catastrophe--forest fire, flood, earthquake that opens a new landbridge, etc. and then work out all the consequences for where your characters live. Is their dwelling no longer usable? Are new fauna replacing old? Is there food enough for the tribe to survive? At some point, you're likely to do an overland migration arc. Think about some group survival mechanics, so that you can challenge the characters to use their abilities to preserve the tribe's integrity.

A good idea as well!

Maybe a volcano eruption/threat that has something to do with fire elementals? Volcano erupting sounds like a caveman's worst fear, because they don't understand what's going on. 

If it’s a caveman setting, maybe it’s just as simple as the cavemen go on their annual migration to the north, as summer is approaching, or south in winter. That way, you keep all the NPCs your party have built ties with, and still get to tell new and interesting stories in different places. Maybe the place they’re migrating to is under threat from an agricultural civilisation, maybe they’re being chased by the friends of these kobolds, etc. That kind of structure could also let you do a load of smaller adventures within the grander narrative of the migration really easily, as the group interacts with the different people/places they come across on their travels.

EDIT: The end goal could also be some big religious festival or other get together for the entire area, so you can build up a big bad that affects all the tribes, depending on how much the party level up on the journey itself.

^ now that’sa thought. 

If it's a caveman setting, definitely do Players vs Nature. Maybe in a nearby area there's a drought or famine, causing the inhabitants to go crazy. Or strong tides burst through a rock wall and a group of sahuagin from the sea start rampaging the area? Try and think about what conflicts could actually occur in a stone age setting, and apply them to your game with a sprinkle of fantasy.
