Mathras is undead but contrary to appearances, he is not an ally of the Deadarmy. Educated and refined, he lived before the time of the Lords of Ice and any known civilization. Mathras has managed to survive as long as he has by moving from one body to the next, once the current one has decayed. During his many years he has had numerous wives and was rather libidinous but no longer gives in to the desires of flesh.
Mathras moved close to the Ice Lord's domain due to the cold helping to preserve his body. His jousting and fighting skills have been honed over the last 3,000 years but he was impressed with Vulcan's abilities. Ever curious and eager to learn new things, as well as alleviate his boredom, decides to join Vulcan's cause.
