endings

Various lose ends:

If you have saved C2, and you lose the final battle, C2 returns to take the throne and saves you. She becomes empress and you serve her as a slave.

R4 Good Ending

Gain R4 by your side, be voted Emperor.

C2 Good Ending

Gain C2 as your wife and be voted Emperor-Consort with her having the real power.

C2 Normal End

Reject C2 and be voted Emperor. Only partially save C2, do not fully restore her by allowing her to meet the current Empress. She demands to be made Empress, when you refuse she drags you into the way out and you're stuck there forever.

If you have appointed a Queen, then your empire lives on and you are honored. If you have not then infighting breaks out and your empire is immediately ruined and you are a laughingstock, known in the history books for your hubris.

C2 Bad Ending

Reject C2 and fight her and lose. She becomes empress and forces you to be her slave by giving you a piece of the demon king's soul.

Good ending:

You beat all your enemies and appoint who you want as empress-consort.
