I really don't understand the problem....
Is it normal that your creature is peeing all the time? Because I never see him drinking...
Same for you character, he/she is never eating or sleeping... is that possible/normal?
And if your creature dies, you can bring him back to live, without going to the Hall of Echoes. You only need the skull.
Perhaps Sassan is such a creature? And she needs the ring instead of a skull?
And why is a logical solution needed... it's a
fantasy game, everything is possible
