Weapon:
Alexander weapons are somewhat unique in that he designed them himself. He wields a pair of extendable arm blades mounted on leather gauntlets intended to provide him use of his hands otherwise. The blades are not long, they are primarily defensive or intended for him to get in close. Additionally he has two small single handed crossbows, each able to fire a pair of quarrels. Due to the size of the crossbows their range is limited and it is difficult to load the lower bolt.

Skills:
Alex is pretty much master of all things mechanical, able to jury rig anything from whatever scraps he can find. He has quick reflects but his more brilliant moments require a period of contemplation. Give him an hour he can achieve pretty much any intellectual task, considering the bigger picture. He learns quickly and innovates by default.
He is a dead shot if given a little time, and in battle he is incredibly quick ans skilled. His strength somewhat lacks in comparison to the children of Ares but is still impressive.

Abilities:
Alex knows a lot about pretty much everything, probably more then would be possible for a normal mortal. He intrinsically understands the inner workings of mechanical devices as long as they follow a logical pattern. If things are overly complicated or there are far easier options that no one seems aware of Alexander becomes notable irritable. Both these are partly natural but certainly influenced by his heritage. The ability to speak with birds is rarely useful, considering most birds don't enjoy the company of humans. The common pigeon offers nothing in the terms of sense. Ravens and some other birds tend to be more intelligent.
He also can actually produce illusions, mostly restricted to himself and the small area around him. In combat these illusions are deceptive and often give him more then the upper hand.

In terms of magical items, no child of Athena would be without them. Since his eyesight isn't particularly good he has been given glasses that allow him to see through walls to a degree, this is something he can control. A small diamond stud in his right ear gives him enhanced hearing. The third and perhaps most useful is a small frosted glass chess piece, a knight to be precise. While it takes a lot of concentration this can provide him a vision of the nearby area from the sky.

Interrogation:
Alex sat unmoving, even if he tried he probably wouldn't be able to escape his confinement. A figure was barely visible in the darkness beyond. It spoke, a slithering, probing voice. "How long have you been serving Kronos?"
The question while it surprised Alexander, didn't provoke any specific reaction other then his blue eyes attempting to follow the interrogator. In contrast he spoke calmly, weighing each word. "I do not serve Kronos." The answer seemed to elicit dissatisfaction and it questioned again with more intensity.
"What have you revealed?"
Again the young man's answer was leveled and controlled, he knew he was bound to infuriate the creature eventually. "I do not serve Kronos." This time there seemed to be no reaction, yet another question as the being has not and probably will never accepted the demigod's response.
"Perhaps I'm asking the wrong questions son of Athena. Have you in any way cooperated with Kronos or his agents to act against the Olympians?" The creature's attempts at out smarting Tyr fell flat, he was almost ready to laugh. Instead he repeated his single response. This time it hissed in frustration. "You haven't answered my question!" The creature snarled and rushed forward, grasping the boy's collar and lifting him against his bindings. This time he didn't say a word, he had seen worse and killed it. Eventually the creature released him and moved back into the darkness. Silence fell and it spoke no more.


Biography:
Alex was never raised with the knowledge that he was descended from the ancient/not-so-ancient gods.. He thought he was just a somewhat normal boy with a single father. His dad, a rather cheerful and active software designer, only told him a specific story of his childhood. A drunken night with a wonderful woman, blankness and then a child roughly nine months later. More precisely a call from the hospital about a recently orphaned baby with a message asking for Keiran Tyr by name, phone number and address. Keiran said he couldn't recall much about the woman, even her name. Alex was close with his father and although there were so many holes in the story once Alexander searched, the boy didn't question.

Dyslexia and ADHD seemed at odds with his natural intelligence. He surpassed most everyone his age, a boy genius causing a lot of stir and a lot of abuse. However, the way he calmly and logically dealt with everything dissuaded attention and he more often enjoyed working or reading then to having company. The only person Alex was close to was his father. That is until his life was completely upturned. Strange events had been occurring all through his life and commonly he managed to avoid the misfortune. At the age of 12 he could not avoid it forever, although he was not the victim. Instead a 'freak accident' caused his father's car to overturn and detonate on the outskirts of Vancouver. The existence of monsters, the Greek gods and his true nature was revealed to him on the same day.

He took the news hard and his arrival at camp half-blood marked him apart from the other demi-gods, even the children of Athena. In time he managed to fit in with people somewhat similar to him. Yet he was still quiet and calm enough to be odd, although many didn't care. He proved to be impressive even among all his half-siblings. He showed a tactical and military mind to rival great generals and a technical aptitude that impressed the cabin of Hephaestus. In actual combat he gained a reputation for swiftness, unorthodox methods and skill. gaining the nickname 'The Blade Trickster'. Even in the eyes of the gods he gained the title of the 'Architect of War', having essentially planned and designed every small attribute the conflict.
