Not to sound lazy, but it's all up to you. You can start from scratch, pick up from Muse's prompt or figure out a way to turn a multi-directional ramble into a story that won't take weeks to complete. Perhaps instead of simply adding to, everyone can talk it out and add what everyone in general wants the story to go? I'm sure that something besides dragon loot would attract Sticks, afterall, they're heroes hired to do a job. Or are they? It's up to all of you to determine the motivation to do something as a party.
