Wayward Cave is located at the very back of Route 206. The entire cave is
pitch black except for a small circle of light around you. It's recommended you
get the TM "Flash" before attempting this area, as it will make it much easier.
There are a few items in the cave, you can find the list below. At the
back of the cave you will find a trainer named Mira. She will ask you to
escort her to the entrance. You cannot use Dig or an Escape Rope to get there.
Once you get to the entrance she will thank you and leave. When you finish this quest and you visit the Battle Tower, Mira will then team up with you.
