You have to defeat dialga. Then you have to go to aegis cave and defeat regigigas.
Then after a few days cressila will appear in your dreams for two nights. After another few days Palkia will appear in your bedroom and bring you to a dungeon.
Palkia tries to fight you but you and your partner fall on the side of the floor. Then you go through the dungeon and fight Palkia. If you defeat Palkia a nightmare freezes Palkia. Cressila will bring you in Plakia's dream and Cressila tells you and your partner you must be destroyed. The real cressila comes and reveals that the other cressila is darkrai. Darkrai says he will be waiting in a dungeon. Cressila talks about darkrai in treasure town. After you,your partner, and cressila go through a dungeon(I think it is called dark crater or something) The dungeon has 15f (I think) then you go through the midpoint and save. The second part has 14f (I think) Then you fight darkrai with his army of pokemon.
I hope this helped!
