Where do I go now (Spoilers)

Where do I go after catching Kyogre? Also where do I get void gauntlet so I can get the last piece of meloetta puzzle piece?

  1. Whirl islands

  2. It’s the hyperspace hole in the mew cave.

Void Gauntlet is the passageway to the place where you fight Giratina and Nyx.

when you get into the hyperspace hole in the mew cave, you go trough and you fight reukra at the end? I don’t know but I found a note in a Pokeball in his base telling me he waits for me where all begin in the mew cave and when I reach that cave, it has magma and only the hyperspace hole to follow withh
