RYUGU-JO: Thanatos » Zurvan II: Region: Ryugu-jo Position: Civilian History: So once upon a time, there was a young lad named Thanatos, an only child. And he lived a quiet existence, helping to run an inn (ryokan-styled for reference but no onsen is attached) that had been in his family for some time. When his aged parents passed, he took over and got married about the same time. But after four daughters were born (Mnemosyne, Hel, Lethe and Hemera), his wife passed on and Thanatos was left with his tiny girls.
After considering his misfortune of no longer having someone to help him, he managed to raise them until meeting dear Ma'at who became his second wife. She would provide all the necessary stability (and a good mother figure for the girls) and, in time, gave him a son. His eldest daughter Mnemosyne married Morpheus, who he happily has welcomed into the family as a much needed stable figure as well. He has zero clue to what is happening with Lethe and Hades. Completely blind there.
He has been pushed to age 40, which isn't much of a leap.
