Before the Books
H'rath, Siv, and Grank were all close friends when they were young. His father was King H'rathmore who was the king at that time which made H'rath the crowned prince. When a great gray owl landed and offered him, as being the prince, first bite of a lemming. However Grank had a vision of a flying snake hidden in the prey and saved H'rath. He and Siv then make a blood oath in which they would never speak of Grank's powers. After his father's dead H'rath becomes High King and Siv becomes his wife, then sometime before the First Collier they have a egg.
H'rath had sent a message to Grank, his good friend who was currently residing in the Beyond the Beyond with a wolf named Fengo. The message was a plea for help asking Grank to come back to the Northern Kingdoms, which were known back then as N'yrthgahr. It also asked him to protect Siv, the egg, and the hatchling of the egg once it hatched if anything happened to him. Unfortunately, Grank was in possesion of the Ember of Hoole at that time and didn't respond immediately until Fengo conviced him to drop it back in the volcano. The moment Grank did this, he came back to his senses and knew that he must go to the aid of his old friends. But, by then, it was too late. He found out that H'rath had been killed and that Siv was on the fly with the egg.
