Older Sibling 

An ancient being known long before the Younger Sibling came to be. This being is often blamed for the younger's misdoings despite not being in the area of the incident or at the area near the time of the event. They are often either antisocial or very mischievous to either the humans or Younger Sibling but are also the protectors of theYounger Sibling despite the annoyance they receive.

Don't blame the Older Sibling for the younger's misdoings or you will get pee in your shoes.
