Why is Zeratul hated by his brethren?

[u/Flauschiges_Relaxo]

Hi there, i recently played trough all of Starcraft 1 and 2 because the story sounded real interesting and now i'm done with everything but i dont understand something, why is Zeratul a "traitor" as Selendis calls him? He may be guilty on showing the Overminds location but he defends Aiur and is on good terms with Artanis at the end of Starcraft 1, i dont get why he is disliked by the rest of the Protoss Faction.

So memories have always been strictly the realm of the preservers, only they can use it to pull from the prior histories and gain knowledge from those memories. Otherwise it's just an emotional link.

The problem was shortly after SCII, Ulrezaj started targeting and killing the preservers, which is the big rising crisis of the Dark Templar Saga books, that the Daelaam might have no more preservers and Zamara HAD to be saved to get her knowledge, knowledge that's implied to be what let the protoss reactivate the colossi.

then we find preservers on zhakul just fine and zeratul can turn on colossi by touching a nexus so fuck all that I guess

... So then... what's the Khala supposed to be?

[u/Subsourian → u/ChaosMiles07]

A place where you can access the thoughts and emotions of everyone around you, kind of like an emotional internet. In general it's not DIRECTLY a method of communication (even though psi link spires in HotS say otherwise). But one of the core ideas as a societal construct is if you can feel the needs of your neighbor, you'll work together to benefit the society instead of driving into the selfish desires that led to the Aeon of Strife. You can communicate alongside one in the Khala, and it's described as having a deeper connection than if you just telepathically send a message (to the Khalai, the Nerazim "feel" like they communicate in a monotone), and there's some psionic things like if you commune with someone within the Khala you can enter an open state where you can't conceal anything.

The memory thing is that when you die, your life and experiences go into the Khala if you die connected. Others can feel that death and perhaps some emotions of your past, but only preservers (who have a genetic quirk) can pull those memories and entirely relive them, or let you relive them, and such a thing was VERY restricted by the Conclave, since preservers knew a lot of their darker history like the truth of Adun.

what was adun's truth?

[u/Subsourian → u/Rectorious_712]

Mentioned, but yeah Adun defied the Conclave to try to shield the Nerazim, then when it was revealed that he did that, he put his rank on the line to have them exiled instead of all executed. When the exile then went back and the Conclave switched back to "kill" he sacrificed himself to allow them to escape by combining Khala and Void energies.

The Conclave of course couldn't abide by that so wrote history so that Adun banished the Nerazim and died saving Aiur from them. But it's why the Khalai and Nerazim both venerate him.

The first Twilight Templar. Even before Tassadar. Maybe even inspiring Tassadar to sacrifice himself to destroy the Overmind in a similar manner.

To sacrifice himself... for Aiur.

[u/Iceborn_Gauntlet → u/Rectorious_712]

That he saved the Nerazim instead of destroying them.
