Synthisit[edit]

It feels like years since I woke up that morning, wondering why my right arm didn't feel right.

From the moment I realized I had come into contact with one of the extremely rare Synthisit Stones by total accident, I didn't know what to think. Although Xandeyr, the half elf who seems to know everything there is to know about this stuff, helped me realize this was a blessing, not a curse, and I knew what had to be done.

Instead of fighting the Synthisit Magic, I worked with it, granting me far more power than even the most Powerful Mage, Barbarian, or Rogue. And now that I'm ready, nothing can stop me in from saving who I love most. Today, I set out on my final journey.

Progressively Upgraded[edit]

As you level up into this class, more and more of you turns into the strange magic-tech known as Synthisit Magic. Fortunately, it's here to help, not hurt.

Synthisit Magic - a quick history[edit]

About 100 some odd years ago, Tyrgretoran Corzaphir, an extremely powerful Half Elf Arcane Tinkerer, went absolutely mad for power after having a "vision from the gods", as he described it. He locked himself in his workshop for over 70 years, scarcely taking breaks or even sleeping, working on a project unknown to not only the general public, but also his Family, comprised of his Wife, Yesseris Corzaphir and only child, Xandeyr Corzaphir. One day, when Yesseris went to go check up on him, as she does from time to time, he was found dead at his desk, presumably from Exhaustion.

Immediately, Yesseris fell into a depression that lasted 12 years, during which time, Xandeyr read through his late fathers books to try and put together what he worked himself to death over; to finish his project. After 4 years of studying his work, he entered his fathers workshop to finish what he had started. And 3 years later, with healthy breaks in between working, he had done it. His fathers project, now simply known as Synthisit Magic, had been completed. All that needed to happen was physical contact with a seemingly normal stone, and it would begin taking over one's body, the more one used its abilities. Tyregretoran had already made tens of thousands of Trigger-stones, spread throughout the globe, but he could not find a way to successfully trigger their full effects until his son came along and fixed it.

If someone ends up being affected by Synthisit Magic, most every town wizard, mage, or cleric knows the tale, and knows where to send you. Xandeyr currently resides with his elderly mother.
