It is very nice what you did with the d666 table, also it is a nice way to give a not-so bitter ending to a TPK, like dealing with the grief of loosing your character by going on one last adventure.

Really good map and setting info! I especially like how you've added some flavor to random encounters with the d666. I'm a big fan of 'what are they doing rn' encounters. Great work!

This is such an amazing concept.  This can be interjected into almost any game in which you have a TPK and the PCs need to try and find their way out of this demi-plane.  I am going to save this for potential future use.  

I really like your layout and your map, and it seems like an interesting concept. 👍 

Love this! Packed full of fun ideas. Any party TPK'ing will have a blast on the island between life and death :)
