Lilandra put Reed Richards to trial for NOT KILLING Galactus when he had the chance, and blamed him therefore for the destruction of the Skrull Homeworld weeks later that the Devourer ate.
It's their modus operandi.
You know what every episode of Scooby Doo taught me?
(And Lex Luthor, and Bill Hicks.)
It's about Land.
Lex Luthor: Miss Teschmacher, when I was six years old my father said to me...
Miss Teschmacher: "Get out."
Lex Luthor: Ha ha. Before that. He said, "Son, stocks may rise and fall, utilities and transportation systems may collapse. People are no damn good, but they will always need land and they'll pay through the nose to get it! Remember," my father said...
Otis: "... land."
Lex Luthor: Right.
(Or in this case space, but it still boils down to real estae.)
The D'Bari system is probably cursed space like the last piece of fried child on the dinner table which no one is asshole enough to take (except for a child of drunk pedo uncle.)
By trying Jean for the destruction of D'Bari under Shi'ar law, that brings D'bari under Shi'ar law, which will clean it up of any folksy doomed mysticism.
Here's the problem with that theory.
In Avenger's Vs X-Men the Phoenix destroyed hundreds of worlds on his way to Earth.
(Although, Galactus is in another universe, so that probably cancels out.)
Meanwhile the war with the builders would have destroyed thousands, if not tens of thousands as systems as wholly as the Dark Phoenix did to D'Bari.
It was something small that happened a very long time ago.
Although the Shi'ar have turned the Phoenix into a power source and even augmented weapons (it was a bloody big sword) with slithers of the phoenix force, which tracks that the avatar of a cosmic force is not the totality of the cosmic force, just like if the avatar of magnitism showed up, you wouldn't expect all magnitism in the universe to vanish if you killed it's avatar (20 years ago there were some brilliant Quasar comics on the subject.).
