Geralt of Rivia

His mother left him at the School of the Wolf in the fortress of Kaer Morhen. There, Geralt was created and trained to become a Witcher. As a child, he passed the Trial of the Grasses. He managed to survive many of the brutal mutations required to become a Witcher. Further experimental mutations greatly increased his strength, speed, endurance, resilience, healing, senses, complete immunity to disease and common poisons, and an exceptional tolerance for pain. This caused his hair to turn white, and he earned the nickname "White Wolf". Geralt was trained by his mentor Vesemir, whom he considered a father. For many years, Geralt traveled across the continent. He visited towns and fortresses in search of proclamations nailed to posts at crossroads with the words "Witcher urgently needed". His adventures took him to sacred sites, dungeons, necropolises, ruins, forest ravines and hidden grottoes in the mountains. During his career, he has killed a manticore, a wyvern, a fogman, an aeschna, an ileucoris, a chimera, a leshy, a vampire, a ghoul, a gravier, a werewolf, a giant scorpion, a striga, a black annis, a kikimora, and several other creatures.
