World of Giants RPG

You woke up to find yourself in another world, though you didn't know it yet. Standing up, you tried to call for help, but... your voice sounded strangely quiet, and you felt insanely tiny. It was then that the ground shook oddly, and guards appeared before you. They were giants, as was the world itself. Words were spoken—another human had been captured. A giant hand suddenly snatched you up, and you woke up in a cage that was empty, yet massive for your size. You had ended up in some kind of castle. Every day, food and water were brought to you, but other people—those who had also been captured—were taken away, though to where, no one knew. All that remains is to hope for survival here.
