Zindarak, also known as the Fiery Messenger, is a mysterious fiery entity that is believed to be one of the Great Old Ones. According to legend, at the appropriate time in the appropriate year, Zindarak will arrive on planet Earth to release Cthulhu from his prison so that he may rise from the ocean to cause the death of humanity and take over the world. However, this can only happen when the stars are aligned.
Zindarak's true alignment is unknown. It is believed that he is a representative of the Fire Vampires, a pyrokinetic race of alien beings that serves one of the Great Old Ones named Cthugha. Other scholars believe he is a servant of the Outer God named Ghroth, which flies past the planets in different corners of the universe and as a result of its voice awakens any of the Old Ones nearby. So, Zindarak is likely to working on behalf of his masters.
