Your new home

In this world, you find yourself as the last immortal being standing. You have been wandering through the desolate landscapes, trying to find a purpose or a reason to exist. As you walk, you see that a new race is building a new home for themselves. They seem to be unaware of your existence and are just trying to create a new life for themselves. You watch them from afar, wondering if they will ever discover you and what they will do if they do. As you observe them, you start to feel a sense of hope and purpose. Perhaps you can help them in some way or learn something from them that will give you a reason to continue to exist.
