OMG, it took forever to remember this! I knew from the Monster Guide it had to be someplace early in the game, but nothing else helped jog my memory…not the map, not the quest guide…all totally useless. Ugh!
But the good news is, I figured it out. Sorry it took so long; you’ve probably figured it out too. Nevertheless, somebody might need the info in the future.
‘Nameless Cave’ is the area where the escape pod landed. Go back to ‘Meteor Forest’ and teleport to the deepest part. Continue north through the door. You should see the pod (where you can heal for free). Further north across the plank bridge is the actual cave area with treasures.
Be silly. Be honest. Be kind.
