The past was decided. The present is being written. What will humanities future hold?

It’s been hundreds of years since the fall of civilization. Nature has reclaimed the cities, and small communities have learned to live differently. Micro societies are now growing food, trading goods, and passing down stories from long ago.

One day, at a bustling trading post, your group wins a curious artifact in a game of chance. It bears a symbol and location from the old stories:
E.C.H.O.
“Enhanced Command & Human Override”

According to legend, E.C.H.O. was a powerful intelligence built to help humanity thrive. Some say it was a force for good that lost control. Others believe it made a choice that changed the course of history. But one rumor just got validated: E.C.H.O. still exists, hidden somewhere inside a forgotten library, buried in time and mystery.

With only the artifact and your knowledge of old tales, you set out to explore the crumbling structure once used to store humanities words, stories, and thoughts. What secrets still linger within its walls? What clues remain, waiting to be uncovered?

Solve the puzzles. Follow the trail. Piece together the past in order to affect the future.

The end was written. The echoes into the future are now yours to decide.
