I have a massive plot hole that I have yet to fill. The players are all attending a funeral for their friend in the Corellian District of Nar Shaddaa. Her working name is Sis. During this time they are presented with her last will and testament, a Jedi Holocron. The Hutts, the Empire, or both as they are both aware of and after the Holocron, seize the opportunity to attack and attempt to take it for themselves.

How did Sis die?/How did she get the Holocron? How come the Hutts/Imperials couldn't steal it earlier?

I'm not exactly stuck but I could use some inspiration.

How did she die? Well, it is Nar Shaddaa. What kind of business was she running? I can imagine everything from shady protection rackets to unsavory rivals trying to take her clientele. If the Imperials and the Hutts wanted her holocron, assassination is not out of the picture from either group.

How did she get the holocron? This depends. Was she old enough to know the Jedi? Maybe one was her friend and she got it from them. If she wasn't old enough, maybe she had a relative or mentor that passed it along to her with all the important details.

Why can't the Empire/Hutts get it themselves? She had it locked in an unknown location. For the PCs to inherit it, it would either have to be moved into the open, or the PCs would have to retrieve it themselves, giving both groups the opportunity to track the PCs to it.

I should have mentioned she is 23 and has been off-world for the last five years. The Holocron was made by Obi-Wan and contains a map to an ancient Jedi Temple built on top of a Khyber crystal cave in an Asteroid.

The Hutt's are led by Jedi artifact collector Grakkis the Hutt and the Imperial's are lead by the first daughter aka Bariss Offee.

Still doesn't rule out the possibility of assassination. Hutts have long arms, and the Empire's are even longer. What kind of work did she do, and why did she leave for so long?

Before she left Nar Shaddaa, she was a street tough. Her role was that of a big sister/ friend to the party.

That's an easy way to make enemies on Nar Shaddaa. Act as a lackey for one guy and you make an enemy out of his rival. Try to strike out on your own and you anger the bigger guys. Run across an enforcer for one of those enemies could end badly, and even a low-level bounty will bring some wanting to cash it in.

The holocron is trickier, but manageable. I image she's not stupid if she recognizes the importance of what it is, so either she recognized it for what it is, or knew and trusted somebody who told her what it was and entrusted it to her.

She picked up the holochron on an archaeological dig somewhere along the border between Hutt and Imperial space (in a disputed area claimed by both governments). One of her mentors from her days as a child found the temple and asked her to come on the dig because she had <insert special skill here>.

Sadly, she (and the entire team) was exposed to a very rare and lethal virus. She and the rest of the team found out about this too late, but not before being able to make arrangements for disposition of their assets. She took the holochron and stored it in a [safety deposit box | gym locker | transit station locker | etc.]. She then placed the key in an ornate puzzle box that could hold the holochron inside it which she bequeathed to the party. If the Imperials or Hutts get the box, they'll only have the key and they won't know to what lock the key fits. The party can figure it out because the location of the locker is related to a key memory shared by her and the party.

The twist is that there were two fast-acting viruses to which the archaeological team were exposed. Both were fast acting (think sarin or some other nerve agent) and were put there by the Hutts -and- the Imperials after their agents (other members of the team) discovered the presence of the holochron.

Surprisingly, though, the combination of the two viruses led to a slower death. The fast-acting death killed both the agents because, before releasing their respective chemicals, they immunized themselves against their own virus - and, therefore, removed the possibility of interaction between the two viruses. They were then quickly killed by the virus the other agent released.

Have you considered the plot twist that she is faking her death? That she knew all those enemies are out to get her so she fakes her death and gifts the players with a replicate holochron, basically setting them up to fight her enemies while she is using the real holochron to figure out Obi's map? Would be a really neat twist if they have been fighting all those factions and then discover the holo they have is a fake!

I like this.

Also, if you're playing things realistically, maybe she just got hit by a speeder or got sick. Leave some clues to make the PCs think she was assassinated, or that she faked her own death, then just let it lead to a dead end.

I thought about the archeologist idea myself and shot it down in favor of using Obi-Wan as the gatekeeper. The Holocron would only be 17 or 18 years old. I'm thinking that over the last five year she's joined the Rebellion as an infiltrator of sorts. I'm thinking her last mission was stealing the Holocron from a private auction.

I have considered having her fake her own death. I'm thinking she had too much heat on her to complete her mission and because of a double agent in the Rebellion she had to get it into the hands of someone she could trust.

The Empire already captured her and is pumping her for information. She didn't have the Holocron on her person and hasn't divulged its location, so they set up a fake funeral and Holocron (complete with a gatekeeper and everything) to lure anyone who is involved with her into a trap so they could capture them and use their lives to break her. the fake Holocron is also a transponder so they can track whoever has it in case they do escape.

A big-deal local crime boss was in love with "Sis". He/she knew that the possession of a holocron would bring down a ton of heat, and so he/she had a subordinate pretend to steal said holocron, and start asking around about who would be interested in buying one. That subordinate then fled to another planet and summarily disappeared. No one suspected that the holocron was still with Sis, and thus no one came to bother her, aside from some concerned citizens who tried to get info from her on the assailant. Sis dies in some unrelated way, and as she's dead, the crime boss that's in love with her has no real need of the fake cover story any more, and takes steps to make sure she/he's not implicated and to cover the tracks of the subordinate.

Part of the problem is that you have your characters obviously receiving the holocron. There's no need for her to fake her death and give it to them in such an obvious way if she's concerned about it getting to the Empire/Rebels. If you really wanted, you could amend my suggested story above to have Sis killed by a rather brutal rebel operative, who is under the impression that Sis was going to give the holocron to the imperials. Then the crime-boss lover would believe that the PCs were involved, and would start hassling them. FUN FOR EVERYONE!
