The Pool of Souls is a location within the Otherworld where users go when they die.
Pass the bleach-white comfort of your pod, there is a dark and treacherous cavern that stretches before you. It is unending and time nonexistent. You cannot travel here alone, user... But perhaps with the guidance of the Good Doctor and your resolve, the unknown may not be as scary as it seems. Should you work up the courage to continue your life's journey and take the Ferryman's gloved hand, redemption is always a possibility.
Brave the road less traveled...
