Guardian Golem

Unevolved

O steadfast guardian, you are my last hope. Grant this old man's last request and guard this secret. Prevent any trespassers from discovering this forbidden knowledge.
—The dying words of an old man

Evolved

Outside the guardian's lair, the forbidden knowledge was passed down through the centuries, eventually coming to be known as magic. Yet the guardian, ignorant of this, remained steadfast in his pledge.
"The world cannot know. This is your duty."
