In the heat of battle, Nathaniel usually dismisses the illusion and takes his true form- a tall dinosaur-like creature with blue skin and thick armoured scales on its knees, legs and arms. Its feet are clawed and its maw opens to reveal an array of wickedly sharp teeth. It wears Nathaniel's top hat and greatcoat, except where the coat was before loose and ill-fitting it now sits easily and tightly. The hat is pushed slightly further up relative to before, revealing Nathaniel's pentacle marking, which glows brighter. The creature's facial features are close enough to Nathaniel's to warrant recognition and a male personal pronoun, though its smile is ever so slightly more… toothy… than Nathaniel's.
Devoted to him despite his abandonment of his son, Nathaniel watched and studied his father carefully at every appearance, and one night was the only soul to observe his father drawing a small but intricate pentacle in the dust, and the bright and strange creature which grew up out of it to sit next to him and break bread. The creature entranced him and after his father left, Nathaniel begged, borrowed and stole every book and every scrap of paper he could find, each new word helping him wheedle and flatter a new snippet of knowledge from the villagers as he taught himself to read and write. One day, as he drew his father's pentacle for the thousandth time and pressed his hand against it, he summoned up a blue monster, the most beautiful creature he had ever seen. The villagers reacted poorly to Nathaniel's new friend, but days then weeks then months of silent communication with a new being caused the youth to mature rapidly, growing in strength of personality and confidence, even as his body remained frail. It helped that as he learnt more and more about his new soul mate his magic also developed; spells were seared into his brain almost as fast as he could learn them, and with the villagers now leaving him alone for the first time in his life, Nathaniel was able to be happy, and even to attain some measure of understanding and sympathy with those who had persecuted him. His new happiness and skills culminated in a single moment as he and his companion- his Eidolon, as the books had taught him- sat next to each other amid the sunrise. A blink, a flicker, and the two fused together into a single being with two minds sharing a deep emotional and intellectual intimacy.
Exulting in his new form, and encouraged by the mind to which staying in a single place was anathema, Nathaniel gathered his few possessions and said goodbye to his mother, still mad but now in the care of the town's newly returned elder, who remembered her and her kindnesses from long ago, and head off for the city, and adventure. And just maybe, his father.
Having grown up with rags and definitely no riches, he takes a certain pride in his personal appearance, exemplified by his black top hat which tends to grow and shrink with his ego moment to moment.
His eidolon is named Bartimaeus, and prefers watching Nathaniel's experiences from behind his eyes to taking a personal hand. Nathaniel does on occasion yield control of the synthesis, usually when he is working on a particularly hard intellectual problem, or when for reasons of grief or anything similar he doesn't feel up to answering the phone call from reality.

Fused Link: Starting at 1st level, the synthesist forms a close bond with his eidolon. Whenever the temporary hit points from his eidolon would be reduced to 0, the summoner can, as a free action, sacrifice any number of his own hit points. Each hit point sacrificed this way prevents 1 point of damage done to the eidolon (thus preventing the loss of the summoner’s temporary hit points), preventing the eidolon from being killed and sent back to its home plane.
Summon Monster IV: Starting at 1st level, a summoner can cast summon monster I as a spell-like ability a number of times per day equal to 3 + his Charisma modifier. Drawing upon this ability uses up the same power as the summoner uses to call his eidolon. As a result, he can only use this ability when his eidolon is not summoned. He can cast this spell as a standard action and the creatures remain for 1 minute per level (instead of 1 round per level). At 3rd level, and every 2 levels thereafter, the power of this ability increases by one spell level, allowing him to summon more powerful creatures (to a maximum of summon monster IX at 17th level). At 19th level, this ability can be used as gate or summon monster IX. If used as gate, the summoner must pay any required material components. A summoner cannot have more than one summon monster or gate spell active in this way at one time. If this ability is used again, any existing summon monster or gate immediately ends. These summon spells are considered to be part of his spell list for the purposes of spell trigger and spell completion items. In addition, he can expend uses of this ability to fufill the construction requirements of any magic item he creates, so long as he can use this ability to cast the required spell.
