Probably make it some sort or Hero's or Legend's guild quest gathering people from multiple fields of experience and backgrounds for an expedition of some sort? Maybe a mission involving a Mahjarrat? Zemouregal being a prime candidate.

Having a solid goal would definitely work. Can't really say much else on that. You'll also have to consider your player demographics and whether or not they're familiar with the setting of Runescape in depth. Balance accessibility with plot. I'd also say you're more likely to get more opinions with a more fleshed out plot summary at least.
