Inktober 52 2021 - Week 35 - 'Yin yang'
Many eons ago, I made a worm god that was based on balance and choice. It would be a creature you sought when in need of advice. They are non-judgmental, painfully truthful and coldly logical. They cannot see into the future (or at least not very far) but They can comprehensively argue each side of your dilemma that you bring to them. One head will take one side, the other will argue the different side. If there are multiple choices, they'll argue as one or add more choices. The blind skull head in the middle will then offer its judgment. You don't have to accept it's opinion, but it will lay out your best options for you, even if you don't wish to hear it.
Whilst its name changed, it was generally called 'Yin.Yang.Yu.' (or Yin-Yan-You, or YinYenU etc.). I do like the idea, they don't really have an official name. One Yin, One Yang and the other for You. Some say they can split in three separate creatures. Others say the skull is not a mask, but really it's face. You will never get close enough to really tell.
