After Damian Quest

I read that he gives the player Shaymin as a reward for helping him but, where is he after we catch Kyogre? I am in whirl islands and I have found a magic Lugia hahaha

Go to erebus town in your dream world

I went there but anyone says nothing, I mean, should I go to a specific house? Others has told me that I will see Damian after rematch E4 but not sure

Yeah, go do the E4 rematch.

Allright! Thanks!
