I’ve broken down Harriet’s monologue from 'The Legend of Ruby Sunday':

“There is the Toymaker, the god of games.
There is Trickster, the god of traps.
There is Maestro, the god of music.
There is Reprobate, the god of spite.
There is the Mara, the god of beasts.
And the threefold deity of malice and mischief and misery.
There are gods of skin and shame and secrets.
There is Incensor, the god of disaster, and her children, called Doubt and Dread.

And standing on high is the mother and father and other of them all. His name has been Set. And Seth. And Sithifer. And his one true name for evermore is...Sutekh!”

The parts in bold are the ones I'm not fully sure about. People are saying they refer to the Gods of Ragnarok or the Eternals from 'Can You Hear Me?'. What do you guys think?
