Keeper is set in a post-human world, after our time on the earth has long since passed.

We open on an island, where, in the shadow of a distant mountain peak, there stands a relic from a long-lost time. Although its purpose in this world has long been forgotten, we instantly recognize it as a Lighthouse.

After eons of lying dormant, the Lighthouse unexpectedly moves. It shudders and shakes, and tumbles to the ground, its ancient masonry cracking apart. But then something even stranger occurs… its broken pieces of rubble reassemble, and it stands up once more — but now on newly formed legs. It has awakened.

As the Lighthouse stumbles clumsily and learns to walk, it finds itself taken with a mysterious sense of purpose and, finding its footing, sets off toward the center of the island, toward the mountain.
