I'm trying to reconstruct how Shadowheart came into possession of the artefact. And then got abdcuted by the mindflayers, but managed to hide it on her person during captivity on the Nautiloid, whereas the Githyanki and the Absolutists knew that it was there, so they went looking for survivors of the crash.

This is what I know and where things seem to be missing or contradictory. It's already obvious (from another thread in this forum) that I missed some dialogue with Shadowheart over the artefact. I put a [?] on these plotholes. Maybe some players have obtained info in the game that I missed and together we can reconstruct the story. Obviously this is all one great big spoiler.

1. The 3 chosen start their plan to enslave the elder brain under Moonrise towers. It is likely that during their research, they learned of the existence of a Githyanki artefact that can block the elder brain, and so they try to find it.

2. The emperor knows about the plan of the 3 and finds the artefact and can enter it, ending up with Orpheus and his guard on the Astral plane. Somehow he manages to survive any hostility from them. Where the artefact is at that moment, is unknown to me. [?]

3. The absolutists are meanwhile also looking for the artefact, as it could disrupt their plan.

4. Viconia investigates the cult of the Absolute and also wants the artefact. She only knows the absolutists are scared of it and that they want it badly, and therefore she wants it also as she wants to defeat the cult.

5. Several Shar commando's are sent out to search and seize the artefact. Shadowheart is one of them.

6. Somehow Shadowheart obtains it. Where ? How did she manage ? Was this before or after the emperor entered ? [?]

7. The Gith'yanki know that the stolen artefact is on that particular Nautiloid and follow it through all the planes to retrieve it. How did they know it, and why couldn't they prevent SH from obtaining it previously [?]

8. The Nautiloid crashes not far from Baldur's Gate, near one of the Absolute's HQ's. The emperor can save the lives of our party members from the crash. He decides he will work with all of you to defeat the absolute, although it is up to Tav to find the others wherever they are and assemble them in a party. [?] Luckily Tav can do this thanks to the telepathic gift from the tadpole

9. The Gith'yanki found the crashed Nautiloid, but not the artefact, though they have clues that there were survivors and now go on the hunt for these.

10. The absolutists also learn somehow that the artefact was on that ship and that there were survivors and hunt for them. [?]

11. At one point, close to the goblin camp, there is a "mental/psionic" contact between the party and the 3 chosen. The artefact protects the party and breaks the contact.

12. Yet, at Moonrise Towers, Ketheric, who was among the 3 that confronted the party doesn't know that they are the ones that have it when they first meet. [?]

13. After defeating Ketheric Thorm everyone knows that your party has the artefact.

I'm curious what you think of this and if you would amend some points or fill in blanks.
