A strong - willed warrior who has lost their way and found themselves in the grips of the darkness. They use their combat skills and physical strength to fight their way through the various threats in the dark realm. Or perhaps a curious scientist who accidentally opened a portal to the world of darkness while conducting an experiment. Their logical thinking and knowledge of science could be their tools to escape.
A young and brave adventurer could be a main character. They are eager to explore the unknown and end up in the middle of the darkness. Their courage and determination to find a way out would drive the story. Another could be a wise old wizard who has some knowledge about the darkness but needs the help of others to fully escape it.
One potential main character could be an ordinary person, just a regular citizen, who is suddenly thrust into the world of darkness. They don't have any special skills at first, but as they face the challenges of the darkness, they develop new abilities like the power of persuasion or the ability to see through the deceptions of the dark forces. Another could be a child with an innocent heart who has a unique connection to a source of light that can help in the escape from darkness.
