Screenshot

From the screenshot. I can’t choose my ending since it lock on jericho ending.

about how to do this.
just do some math. save some nest / lair to boost the value
in this play i allied with anu and synderion first and jerico last.

Is the a different ending depending on who you ally with? I had 100% with all 3 as well but everything had to with with the disciples.

no, it depends on the final faction research you complete !
