Kalorithian was born in the High Forest to King Valkor Silvertree and the now deceased Jareja Anthaliss. While playing in the forest Kalorithian discovered a mysterious magic using elf in the woods near his house. Curious, he went to him and asked him to train him in the Weave touch. The elf said, "Why yes, but only if you will leave the forest with me." Not wanting to pass up his chance, Kalorithian readily agree to the condition and left home.

Together, the pair traveled all over the North, Western Heartlands, and even the Outer Planes. They finally settled in a secluded section of the Elven Court, where he finally began to learn the Art at its higher levels of knowledge. Scarcely more than a decade later, they where found and attacked by two scores of tanar'ri from the nearby Myth Drannor. A fierce battle occurred the likes that haven't been seen there since in the recent years. The remaining tanar'ri fled, leaving Kalorithian's mysterious mentor mortally wounded. As the elf died, Kalorithian told him his real name, Zathian Fenrok.

Kalorithian would later learn that Zathian was the most powerful enchanter to ever live outside of Evermeet. Seeing the weaknesses of being solely a wizard, Kalorithian took his mentor's belongings and began training as a fighter with the warriors of the Elven Court. Upon completing his training, he left with the Grey Eagle adventuring band and traveled the North once again, even learning a little of romance and bardic knowledge from a female moon elf in the company.

Meanwhile, ever since he had left home his father, who had contracted a cursed Halruan sorceress by the name of Stiletto to find him, was searching for him. Her confidence and beauty quickly struck the elven leader, and by the time she found Kalorithian she was his official consort and had a baby, the only apparent heir to his father left to him. Cylindria soon found the true heir to the green elves, after he and his companions left the elven woods.

As his party was eating eveningfeast, Kalorithian spotted a tall woman of human blood of incredible beauty, yet an odd and somewhat elven aura about her, approaching his table. When she reached them, she informed Kalorithian that he was sent for by his father, who was in line to become king of the united clans of wild elves of the High Forest.

They all left immediately, the Grey Eagles vowed to see the Prince and his escort safely to their home woods. His female bard friend, however, left when they departed from the High Forest, although she promised to return after spreading the word of the green elf union and the stop of the Retreat, even if from only a small portion of the Realms. It is at this time that Stiletto told her true name, that of Cylindria Blade to Kalorithian. She gave this information to him, and started to continue his instruction in the Art, continuing from where his mentor had left off.
