Arokh was bonded to Heron in the Order. They both fought in the war against the Dark Union. Heron died in the war after banishing Navaros, leader of the Union, out of the world. With his master dead, Arokh retreated to his lair, where he fell into stone sleep for six-hundred years.
He was re-awakened by the warrior woman, Rynn, who needed his help to save her brother and avenge her village. He again underwent the ritual of the Bond, uniting his soul with Rynn's.
When Arokh was awakened by Rynn, he showed rage upon learning she woke him to help her rescue her brother, but was impressed by her bravery. After the Bonding Ceremony they set off on an adventure to rescue her brother and defeat the Dark Union. [Source: wikia]
