Notable Miscellanies

Main quest

After arriving, there is nothing immediate that happens. However, upon taking the southern path, Scientist Richard will stop you and ask that you hear him out. He explains that there is a Pokémon causing trouble that is affecting the islands tourists and he asks that you help. He tells you to meet him at the cave entrance in Sevault Canyon.

Scientist Richard will tell you of an artifact that can handle the sandstorm this mysterious Pokémon is causing. It can be found in the ruins to the south.
Once the artifact has been found, he will let you enter the cave.

To the south of Sevault Canyon, you will find Tanoby Ruins. This is a series of small desolate islands. The second island south from where you enter is the one you need to enter. Inside, you will find the needed artifact. After retrieving it, return to Scientist Richard.

After showing the artifact to Scientist Richard, he will move from the entrance, granting you access to the cave. He will warn you that the Pokémon inside is very strong. It will be level 120 and, after defeating it, will leave behind a Smooth Rock.
