It actually means a little more than that, though that comment is entirely accurate.
This planet was only kept in existence because of very, VERY strict laws, enforced by the Elder, to remove all knowledge of the Force from his people. Only this activity kept this planet alive. True stories of the Jedi and the Sith and life inside the Galaxy were forcibily turned into myths. Only this could possibly keep knowledge of the Force from the people.
Until, of course, a bunch of people arrived and messed that up. As soon as these people learned of the Force... the game was up. The instincts that all of them knew- as Jeren'Toc told you, he instinctively KNEW you were right- were unleashed, and this war started.
Gundark, you slump to the ground. You can feel, every few seconds around you, another death. In this war you have started. And you realise now what you are kicking yourself for not realising earlier.
"The Force is one of those things you should not speak of," said the Elder. It does not exist. Not for these people. To hear it will be death for them." He TOLD you. He told you what would happen!"
"You will oblige me by not spreading any more poison in the minds of my Council Members... I mean poison as in it is lethal and you have filled him with it."
The poison... is YOU. Everything you were telling Jeren'Toc was further dooming his people. The Elder was trying to stop you!
"Your words are heresy, and your punishment will be death. You will make my life far simpler by not talking any of the things you tried to talk of to me or your captor. If you do, I will also have to execute all those that hear you and I would rather not do that."
He HAD to kill you! It was the only way he could stop this from happening!
You all thought he had the wrong idea about who you were, and what Jedi did. But he knew!
"I know exactly what and who you are and what your nature is... I also understand what you represent to this world. Which is the destruction of everyone in it. So do not think there is anything you can do to deflect me from this course."
Gundark... how many people have you had to kill for the Greater Good in your career? You carry a Lightsabre- an acknolwedgement that sometimes in your work you must kill in your defence- or the defence of others!. The population of a planet- how far would you go to protect it? Your planet? Your people? Gundark- the Elder is a Light Sider, protecting his people as much as you protect the Republic. He knows who and what you are. But...
"That makes precious little difference to the reality of the situation... regardless of why you came- you should not have done so. That mistake means your deaths... why shouldn't the Force harm the innocent? That is all some people use it for. Please, your attempts to convince me otherwise are futile. I must kill you before you kill my people. There is simply no other way"
He was saying yes, you are Jedi, the good guys- so what? You will still kill my people if I do not kill you first.
"I knew what I would have to do before you came, when I sensed you would, and I am just as certain now"
He spoke with certainity not out of arrogance- but because he foresaw it! And it was not just you he was not ignorant about. You thought he did not know the threat he faced. Of course he knew!
"You do not need to tell me how much of a threat the Sith are... or how many of my people will be slaughtered trying to excise them. But excise them we shall, as we shall excise you, before it is too late."
He could control it if it was just Kuylen. He ordered his people not to fight. He staged the show trial of you to ridicule the word Kuylen- and you- were spreading. He might just have stopped it- with the slaughter of many trying to stop Kuylen, but he might just.
If only he had been able to kill you.
Gundark, you can see it all now. The Jedi arrive here in the midst of the Sith War. An entire people who can use the Force! How wondrous! What marvellious allies they would make! If they could be properly trained and taught- as the Jedi could do- what a great thing it would be! And how willing would the Zeitonians have been to listen!
But then the Sith came, bringing the other side of things. To fight for the resource of a planet of several billion force users? What lengths would the Sith NOT go to for that? Look at this world! Look at the surface! Just how BIG was the war here?
And how long before the Jedi, seeing the division of the Zeitonians then as now, realised the same thing as you. That all they could bring these people was death. And so what did the Jedi do?
"And now we are paying again for your broken promise."
Paying again- what they paid before is on the surface. But the promise? The Promise of the Jedi?
"The promise was made and recorded in perpetuity. But as ever, the Jedi fail us. And now WE pay the price."
It can only have been one thing.
No Jedi will ever again set foot on Zeiton
Gundark... what have you done?
"You should stop your pursuit of Kuylen," said Grevor, on Malastare, what seems a lifetime ago. "I sense nothing good can come of it.". So did the Council- reinstating your pursuot only when politics made it impossible for them to refuse.
And the Astrolabes!
"I shall tell you what you need to know on once condition," said Ascar. "That you still want to go after what I am about to tell you... those Astrolabes were in perfect working order when the Jedi found them. They were disabled, on the orders of the Jedi Council."
Gundark- it wasn't the Mausoleum. it was the PLANET! The Jedi must have known! They KNEW where the Mausoleum was! They knew that any Jedi trying to find it would go to Zeiton and that must NEVER be allowed! They knew that the very existence of Zeiton must be struck from all memoery. Because they knew there was only once chance of justice for Zeiton- for its people to be left in peace, the Elders ensuring that knowledge of the Force never returned here.
Damn it... Demnos... Demnos KNEW. THAT is why the Mausoleum is here! He built it here not because it was hidden from the Jedi. But because he knew this was the one place in the Galaxy that the Jedi would never ever go to!
The Mausoleum was never not found. The Jedi could just never go to it. For to do so would be risking genocide, which the Jedi would never do. The Cult of Demnos, up until the end of the Sith, operated with impunity.
In the millennia since all this happened... it has all been forgotten. Like Zeiton and the Zeitonians. Until now. Until you followd Kuylen here.
WHY didn't the Council stop you, Gundark? Surely THEY knew?
(of course, players may wan to remember this thread at this point...)
