You woke up in a strange place, a chill ran down your skin. After getting up and getting used to the space, you start to hear strange music and someone's slightly mocking voice

""Congratulations, loser! Welcome to Hades! Your death was so stupid that you won't be able to move on until someone here is willing to help you with it!"

What does this mean? And whose voice is this?! You need to think quickly, standing still will not lead to anything good
