I really appreciate you advice and help people, thank you all for the help you provide.
I read through everything and I realised that I could not give the facts as they are, so I drove the path away.
I will make a sum up of the clues - and add some new ones - in one post:
- The PCs do not belong to this timeline.
We started the story in custom world with another DM. After the 1st session, I picked it up to continue the scenario. I found a way to play in Eberron. The story started with the PCs exploring an old ruined village - located in the version of Eberron that Sharn was not the city of Tower (the previous custom world) were a lonely artificer was having experiments for time travel, in order to go back and save his wife. After some flash backs - the PCs were seeing the village as it was 20 years before and vice versa - the "travel machine" was destroyed, locking them in an alternate timeline, where the machine never existed. That's the Eberron as it is now.
- The first person the PCs met is their current patron.
The PCs made their way to Sharn as it was the nearest city they could see - that was their birthcity in their real timeline - and they got in trouble. That's when they started to do a digging and, trying to find a way to go back to their timeline, met their patron. He is a kind young man, and is trustworthy and I want him to like the PCs.
- The player's father is NOT his real father
The Object X is now safe in the hands of a player's
alternate father from this timeline, who happened to have lost his son (the player) and his wife during the birth. So, after the explanations, the father met the son he never had, so it's kinda cheesy to use the father as traitor. At the moment at least.
- The Object X is important and dangerous, and 3 organizations are after it.
Only the Master of the kind patron is aware of what X can do. The other organizations, only have a tiny idea, but still they want it for them. The PCs found X by luck, when they were after another relic for their patron. They knew of a long lost item (the X), as they knew that their patron was after it.
They kept it secret to make more money because they met the other organizations during the "quest" for the relic (not the X) and they thought that the reward for something that so many people are interested is trivial.
- The Patron was not aware of the difficulty the PCs had to find the relic.
The money that he gave to the PCs was the "budget" that his Master provided as reward for the relic. He also paid some extra (his own money) in order to keep the PCs happy, but still the PCs do not trust him now.
- X is really important for the plot.
The Object X must somehow be back to world, so that the plot reveals. Think it like in Lord of the Ring, if Boromir had taken the Ring from the hobbits and didn't die there. The Ring should be again somehow back to the world, in order to continue the plot.
- X cannot be tracked by Divination.
At least without a serious reason. Whoever tried to use Divination to track the location of the X all these years, he failed because the crypt was protected. Now It maybe can be tracked, but there must be a reason. The only one who is aware that the PCs know information of the location of the X (that's what they told him, they did not say that they have it) is their patron. Probably his Master will know it in a couple of days since the PCs asked their patron to let his Master know that they want a huge amount of gold for the information.
Also some of the PCs even think to keep it 100% secret, until they know the purpose of the other organizations (what they will do with X) so that the PCs chose who to give it to.
The idea of giving it to none was even an option.
Knowing now, I hope you see why I am in a dead end, and why I feel that the players are in control of my story. They also know that the information they have is invaluable to 3 factions, which make them feel immune to death, since the secret will be lost.
Now you know everying I do.
I thank everyone that already helped and in advance anyone that will help!
Cheers to all
