A solo game with allies
Steam describes Fading Echo as a solo game in which One encounters a small crew of allies across Corel. It says their presence shapes the world, stakes and cost of failure.
Do not turn a premise into a roster
The store description does not name every ally or provide a complete biography list. Use the game and official channels for those details.

Q: Is Fading Echo multiplayer?
Steam presents it as a single-player game; its story includes allies rather than co-op claims.
