Operation Golden Rule of Love
SPOILER!
Zaibach's love experiment targets the emotional triangle around Hitomi, Van and Allen. Van nearly confesses what Hitomi means to him, but he says it badly enough to leave her hurt. Folken's machinery then amplifies coincidence around Hitomi and Allen, putting the right meetings and emotional openings in front of them until the attraction Hitomi already feels becomes the outcome Zaibach wants.
Van arrives in time to see Hitomi and Allen kiss.
What changed
This is the Fate Alteration Machine succeeding in the narrowest sense and failing in the larger one. It creates separation, but not a stable future. Hitomi's later choices come from confronting what she actually feels, not from accepting the relationship Zaibach arranged around her.

Fortune Blood
SPOILER!
Fortune Blood is Zaibach's attempt to manipulate luck directly through Naria and Eriya. Folken allows the leopard sisters to undergo the experiment because the artificial good fortune should make them almost impossible for Van to defeat. For a short time, it works. Accidents favor them. Attacks miss.
Escaflowne cannot simply overpower a battlefield where probability keeps leaning the other way.
Then the luck turns. Their bodies begin to fail and the same experiment meant to protect Folken kills the two people most devoted to him.
Why it matters
Naria and Eriya are the point where Folken can no longer keep Dornkirk's theory at an intellectual distance. Fate Alteration has a body count he loves personally. Their deaths finally break his loyalty to Zaibach.

Celena Becomes Dilandau
SPOILER!
Dilandau is not simply an unstable Zaibach officer with a mysterious past. The late-series reveal shows that Zaibach's experiments transformed Allen's kidnapped younger sister, Celena Schezar, into the identity the audience has known as Dilandau. Jajuka knew Celena during the years of experimentation and remains loyal because he remembers the frightened child underneath the commander Zaibach created.
The transformation begins breaking down as the final war approaches. Celena re-emerges, is pulled back into Dilandau, and finally returns after Jajuka dies protecting them.
Why it matters
This is Zaibach's philosophy made personal in the ugliest possible way. The empire does not only move armies and probability. It treats a person's identity as material that can be rewritten for a desired result.
