Nymixthriin was but an egg with Ithuliak descended upon his mother's lair. The matronly silver fought valiantly to defend her unborn children, but the great black wyrm proved too great a foe and slew her, smashing her eggs and stealing her hoard. Nymixthriin would have joined his poor siblings, but through a strange twist of fate, Ilthuliak's acidic breath brought down a cave wall in the battle, sealing the unborn dragon away. It would be some months before Nymixthriin would break from his shell and crawl into the gruesome aftermath. With nothing and no one to call his own, yet burdened with an unexplained desire to bring justice and law to this strange land, the hatchling set out into the wide world in search of someone to mentor him.
The wyrmling flew west over the Tors and into the lower Kamelands in search of companionship. He wandered alone for the better part of two years, his silver scales losing their youthful luster as he sank into the loneliness of depression. Then one day, as he was resting on the shore of the Tuskwater, he was attacked by a man clad in a helm of stag horn. The powerful man easily defeated the young and inexperienced dragon, and dragged him, barely alive, back to his fort on the north shore as a prize.
The Stag Lord's men said that they should skin Nymixthriin and sell his hide, but he had greater plans for the dragonling. Locking him in a dank cell, the Stag Lord came to the dragon each day and beat him bloody. He belittled Nymixthriin, starved him, and stole what little pride the young dragon had left.
Then one day, the cell door opened, and the Stag Lord threw in one of his underlings, a man that had not been completely honest about his take that month. "You must be hungry," the bandit leader growled. "Eat." And eat Nymixthriin did.
After that, the beatings stopped, and suddenly fewer bandits laughed at Nymixthriin from outside of his cell. He had become an instrument of the Stag Lord, a tool of justice that cut down unruly or too outspoken members of the bandit gang. For the last five years he has resided in that cell, all the while hating the Stag Lord. With that hate, however, he has grown strong.
