Insithryllax

Description
Insithryllax was a great wyrm black dragon that was present in Innarlith in the mid 14th century DR. He was a close friend of the Thayan Red Wizard Marek Rymüt with whom he assisted a project to breed a mutant cross between a black dragon and a fire drake

Personality
Insithryllax was quite comfortable in polymorphing into a human form, which he often did so and used it to enter human society.

Relationships
Marek Rymut had initially cast a Charm monster spell on Insithryllax during a battle and enthralled him. The spell eventually wore off, however, and the two of them developed a natural friendship with each other that lasted for decades. Insithryllax accompanied Marek to Innarlith when the Red Wizards sent him as their agent to the city. When Insithryllax was enthralled, other red wizards saw him as either an asset or a threat, depending on their relationship to Marek.

He had become the father to a number of children when he bred with female fire drakes as part of Marek's project to breed black fire drakes, however, he didn't have deep care for his offspring and would feed them to each other when they ran out of food in the nursery.

History
In the 1330s he was present in a swamp in Thay where he had a tribe of lizardmen who obeyed him. This tribe had failed to pay their taxes to Thay and as a result the Red Wizards sent Marek and others to go after them. Marek and his comrades battled the lizardmen before Insithryllax appeared and Marek's companions. Marek used a charm monster spell on Insithryllax and enthralled him. Insithryllax then returned with Marek to civilization in 1336 DR and eventually wound up with him in Amruthar where Marek would receive his orders from the Tharchion to go to Innarlith.

Marek was sent to Innarlith in 1340 DR and Insithryllax accompanied him. The charm monster spell eventually wore off in the years that followed, but Insithryllax chose to stay with Marek.

Eventually Marek concocted an idea to try to breed the mutant offspring of Insithryllax and female fire drakes, which he called 'black fire drakes'. Marek found an underground area beneath the sewers of Innarlith that had formerly been used as a thieves' den and made it into a nursery for raising the young. Insithryllax mated with the female fire drakes and had many successful offspring with them.

However, Marek had underestimated the amount of food that the black fire drakes would consume and this led to them needing to devour each other in order to survive. Insithryllax maintained an order to this by killing off weaker ones to feed to the others.

In 1361 DR some of the black fire drakes found a way to escape to the surface, where they created destruction and mayhem across the city of Innarlith, before they were either killed by the city guard or transported back to the nursery by Marek. Eventually Marek concocted a new plan where he carved out a pocket dimension out of Fury's Heart which he called the Land of One Hundred and Thirteen and used this to raise the black fire drakes. Insithryllax then went to the pocket dimension to help with raising the offspring.
