I think you messed up with Gisette, for the peace in Revaire ending I would avoid her unless you're playing with at least 75 manipulation. (and truthfully I wouldn't go this route without it for the legacy ending).
First I greeted Sayra, Ria and Jasper friendly
invited them to eat
When talking to Ana click Gisette want to talk to u for 5+ manipulation
NEED TO TALK TO ZARAD, CLARMONT, EMMET AND JARROD (for peace in Revaire ending) (would immediently go to the first introductions don't waste time on hair and makeup)
Save Penelope from Jarrod in the first introductions when talking to Clarmont
rebel secret 1 in kitchen
made Kaytia's legacy my goal
Host a event and invite Sayra
------week 2 --------
Met Clarmont in the garden
meet Jarrod in the training room
forbidden room (for trial- you need 100% to get rebel respect)
cliffs (rebel secret 2)
--------week 3-------
Befriended/romanced Jarrod and rejected him, (needs 450 persuasion).
accept Clarmont's proposal
Host an event and invite Sayra
-----week 4-----
Say 'I'm sure Imogen is innocent' in the supper after the murder
visit crime scene in first day and examin everything
find alibis for Imogen
go see the other crime scene and click rummage through everything, and click everything but the water option
(70 manipulation of 50 courage needed to talk to Kade)
He's the murder ordered by the island natives. He used a rosethorn, made the horses disappear, Framed Gisette, (idk the rest off the top of my head)
On the last day Zarad with enough friendship will meet u and tell u about the weapon used and u have to go to the servants quarters to check for it.
Achieve a perfect trial, by clicking the ace up my sleeve
Go on dates with Clarmont
-----week 5------
go to servants quarters, Mrs White will give u a nod if u have MAX approval with the rebels.
go on dates with Clarmont
and do the break up scene with him again.
-----week 6-------
Grind poise for the negotiations
----week 7-----
no need to host the ball
follow the wiki's advice on how to bring peace in Revaire, for the legacy ending u need to convince, Gisette, Jarrod and Sayra
