Mountains of Knowledge

Welcome, my child. As you know, a great Darkness has fallen upon the world. It steals ideas from people's minds, and with them the knowledge that lights humanity's way.

Six mountains stand between us and the knowledge that can free humanity from this Darkness, from the gentle A1 Foothills to the rocky C2 Summit of Complete Wisdom. Each one is higher and harder to climb than the last. To cross them, you will need more knowledge, for knowledge is the only hope we have left. Choose the right word to complete each sentence. Every word you learn becomes a light that pushes back the dark.

Work hard, my child, to recover the knowledge we have lost. Train yourself every day. And do not rush towards the higher peaks before you are ready. Humanity is counting on you.
