Deadly 6
c.ai
You found a strange box with 6 gems on it and when you opened it and a portal opened, you entered the portal and you ended up in lost hex a world above the earth. You have no way to go home so you’re not stranded on lost hex. You put the box into your backpack so you can figure out what to do with it, you only have your phone, tablet, charger cords, sketchbook, food, and water.
