It Is Those Who Do Not Seek Immortality That Eventually Find It
Tolend Dathar is a Legend among the Asylian People. Legends tell of a hero by that name whos task it was to protect the young princess, during the darkest days of the kingdom. Against more then a thousand men that hero stood, and for seven nights and six days he fought, until he alone stood upon a mountain of corpses upon the seventh dawn, holding the young princess in his arms.
The Tolend Dathar of today is a Guardian, one of the protectors of the royal line, a personal bodyguard to the Princess of Asylia. He is a silent man, saying nothing. He is ever alert, every ready to protect his charge. Tolend Dathar is ALWAYS with the princess, even while she sleeps, even so when she bathes or otherwise performs ablutions. Such is the purpose of the Guardians, that the royal line is always kept safe.
The equipment of the Guardian's is classified, to the level that only the current king is aware of their standard arms. However Tolends armor is a unique matter. The armor is fashioned entirely from Titansteel, a metal alloy with a density approaching that of the core of a black hole. Asylians generally use the material to make their warships, as the weight of the material precludes it being used for other means.
Tolend however is uniquely gifted. As a boy he was blessed with inhuman levels of strength, though he lacked severely in a number of other capacities, speech and higher learning among them. Military training drilled into him through sheer tenacity the means to fulfill the one mission he would be given, protection of Halena Asylia. His armor's weight makes him impossible to knock down, his sheer ungodly strength allows him to move with ease. He is the absolute perfect shield for the princess, and such is his only purpose, and the only concept he is capable of understanding. Mathmatics and science, tactics, strategy, none of these mean anything to him. To say he is merely a pit bull in human form is not actually accurate though, as a pitbulls are actually quite intelligent.
Tolend does not have strategy or tactics in mind during combat. His solution to most problems is to grab it and break it, something he is well and truly capable of doing.
History
What few people in Asylia know is that the legends that many people think of when they hear his name are actually depictions of his own history, for the Man known as Tolend Dathar is in fact a true immortal. Though Asylians are a very long lived race, they do age and eventually die. Tolend however is unique, in that he can no longer truly be classified as either living or dead.
Eons ago, when Asylia was still a fledgling kingdom, a young man was born, who was strong of body, but suffered a curious defect of birth that rendered him voiceless. For Most asylians this defect is rarely considered problematic, as many of the species are able to use Telepathy, as indeed this young man did. However another facet of this defect is a weakness to infection.
Tolend Dathar was indeed infected, by a unique virus that consumed his flesh, absorbing and taking over the entirety of his body. He died, and was thence controlled by the virus, that sought more victims as all viruses do. An outbreak was prevented by the might of the asylian people, who's magic quickly rendered the creature immobile. Studies were made of it, and over time a sort of cure was developed.
Tolend Dathar cannot be considered living, nor can he be called dead. He is in between, and nothing short of absolute dissolution will eliminate him. Such is impossible however, as the virus has rendered each individual cell sentient and willfull, meaning that when a threat to it's existence is determined, it shall separate and scatter it's constituent parts. More than one enemy of the kingdom has discovered this, to their dismay.
As if that wasn't enough, the virus is incredibly aggressive. Most asylians are rendered immune from infection not by actual medical practice, but by the fact that the asylian physiology isn't strong enough to survive infection. when an Asylian becomes infected, their bodies often simply give out and die, taken the virus with them. In most other living or organic creatures, the virus's aggression overwhelms biological, and even biomechanical, systems within hours. Nanite defenses have proven useless, as the virus assaults the nanites themselves, and somehow breaks them down to use for it's own purposes.
Tolend Dathar became a hidden asset to the Asylians, one which the king, in a bout of selfishness after the loss of his wife and birth of his daughter, decided to use for the sole purpose of protecting his daughter. He had Tolend trained and programmed to fulfill only one purpose, ensuring his daughter would never come to harm.
