Birth: The Flames of Destiny.
Azolg's story really does begin at his birth, and what a birth it was. A horrific scene befell his mother as she went into labor and by the clumsy hand of the attending young Shaman, the hut went up in flames. As the flames spread hard and fast it became evident and obvious that they weren't going to make it out alive. Heat licked at his mothers skin, and in her desperation and fear she called out to the only thing she could think might help - The Spirit of Fire. Begging, screeching at the to of her voice she pleaded that while he own life couldn't be saved, if only her child could be spared such a death before it even had a chance to breathe the air.
And fire heard. And it responded.
When the flames died down, and the hut was a smoldering ruin the Mag'har managed to get closer inside, find out just what was left. Azolg's father Drakkuth cleared the half-burned wood to find the embers of his mates bones, and in it a screaming cub completely unharmed. A brand etched across his chest, seared into his flesh, depicting the sign of Fire.
And it was on this day that Fire claimed Azolg. It had heard his mothers cries, and decided that if it was going to keep Azolg alive, then he'd serve it for the rest of his life.
Youth: Life as a Mag'har.
Azolg's life was quite uneventful as he grew up living with the Mag'har. He kept a close relationship with his father, mainly to help with Drakkuth's own grief at the terrible accident. They became close, far closer than most father and son relationships, and Azolg would soon desire to follow in his fathers footsteps as a Pyremaster himself. Growing into his maturing years, he was around when Thrall came to visit Garrosh in Garadar. Seeing Green Orcs for the first time, and this supposed 'New Horde' intrigued him to no end; but there would be no time for him to leave until he was a fully fledged Pyremaster.
With Garrosh's departure to join the New Horde, time passed on and soon he had finished his studies, and even surpassed his father in his Pyremastery. His connection to Fire gave him an advantage that hadn't been seen in an age; such a boon was perfect for a Pyremaster. And as time went on he replaced his father, whom retired from most of his duties as age caught up with him.
The Rebellion: To Oppose A Tyrant.
When word reached the Mag'har that Garrosh had lost his mind to power, Azolg decided that he could stand by no longer. He had a power that could be used to fight, and Garrosh had come from the Mag'har. With his fathers blessing, he joined the Rebellion and helped overthrow the reign of Garrosh. After spending a little time in Orgrimmar, exploring the New Horde and the diversity it bought found the Red Blade Tribe. Deciding that he'd like to see just how different Tribe life is he joined up as a New Blood.
Back during this time, he kept his face covered by a skull mask, and stayed on the fringes of the Clan. Never interacting too much to get attached and more of an observer than anything else. He never took the Oath, but he held two pyres during this time - Sadok Sharptongue and Grogona Marshfang. The Tribe had come to trust him despite his distance and caginess; and to hold pyres for Orcs of such high standing was an honor he could not turn down.
It was during this time, and the Legion invasion that his father fell deathly ill. Abandoning all pretense, he returned home to be by his fathers side for Drakkuth's final days. The pyre he held when his father passed was perhaps the hardest one yet.
