Fastolph was born to Poddmuch and Galbeena Boffin in the Shire of Wistfolk on the outskirts of Thera. Raised as the son of a farmer, Fastolph began hearing the tales of travelers from distant lands. After Fastolph mentioned his desire to leave the Shire to join the Burrfoots, Haricots, and others on their travels, his father forbade Fastolph from leaving his brothers and sisters.

Late one night, after Fastolph's brothers and sisters had gone to bed, he left the earth dwelling in search for a purpose; the life of a farmer did not interest him as much. The grandiose tales of adventure were too much for him to ignore. Little did he know that life as a young halfling was not the easiest of lives.

Floating for many days on a makeshift raft provided by a cousin, Fastolph was ravaged on the Southern Sea by waves and creatures he had never seen before. He used a paddle to attempt to ward off the nasty fish that jumped up and attempted to take his flesh. At some point in time he was knocked unconscious and fell into the water. He awoke in the sewers of Glyndane in the presence of a man wearing a tattered leather armor. The man, Fastolph came to find out, was one of the most skilled thieves in all of Thera. He taught Fastolph everything he would need to know to survive on the streets.

After a few years, Fastolph began to adventure out, seeking to capture some of that fame he heard about while growing up in the shire. Using the talents learned from his mentor, he began to use his craft to "borrow" things from those whom he felt had done very well for themselves. His small size made him adept at lurking in the shadows, ready to pounce on the unsuspected target he had been watching and studying.

Fastolph found that people were too busy thinking about themselves to even care that he was borrowing things. He never failed to get what he wanted, and quickly mastered his craft. He began a new mission: to equip thieves with the tools of the trade so that they, too, could survive on the streets. He understood the dangers and felt he could do as much for them as his mentor did for him.

Fastolph roamed Thera in search for something greater than his experience and strength. And then one day, he finally found it. Or rather, he found her… an elf of indescribable beauty who immediately stole his heart straight from his chest. Fastolph had never felt this way about anyone. The music that poured from her viol taught him that his craft was not the only purpose in life. His purpose was far greater, more intimate than anything he had known.

Fastolph began to question his own ethics. He began a quest of purifying his heart that was darkened with the blood he had spilled so much of. He strived to cleanse the impurity that plagued his mind, so that he might feel worthy of the elf his heart yearned to be with. He asked every paladin and cleric if there was a divine one that could grant him forgiveness for his transgressions. He overheard that he could seek such a quest in the Sands of Sorrow.

Getting lost in the Sands of Sorrow, Fastolph stumbled upon a guardian ravaged by hatred and contempt. Upon examining the guardian, he saw two things of great intrigue that caught his interest--two semi-translucent necklaces that throbbed with energy. Fastolph decided to just take a look at them, if only for a moment. Curiosity overwhelmed the little halfling, and he decided to wear the necklaces around his neck. He immediately noticed a surge of overwhelming energy that coursed through his veins.

Little did Fastolph know that he stole the fabled necklaces of power that laid with their master's guardian, the Lord of the Serpent, Nebhotep. The necklaces allowed Fastolph to move across Thera with a mere thought. He rejected the demand from the Lord of the Serpent to return the necklaces, and offered to sell them at a reasonable price. The vile Lord of the Serpent was unable to take Fastolph's life by divine means: earthquakes, rats, and plague. The necklaces appeared to keep Fastolph's body in the fight. As a last resort, the Lord of the Serpent used his power to send Fastolph to the final sleep and inadvertently destroyed the necklaces with the surge of power that left his fingers.

The surge of energy overwhelmed Fastolph as he approached the Weave to unite with it like so many across Thera have done before. But the energy would not let him stay. It filled Fastolph with renewed vigor unlike any that he had experienced before. It was not until the Lord of the Serpent himself screamed with anger from the destruction of the necklaces did Fastolph know that he had been imbued with the life of an Avatar--immortal in body and in mind.
