Why are all of the mages either originals or younger than 10,000? Is there a reason for this that I didn't notice?

Sorry btw, I do realize my form is a bit weak, I could probably make it better, but I want to get in on this before the story gets too far. Hopefully it's good enough and there aren't any gaping holes or major issues.

Name: Osias Dryton
Age: 117,876
Species (witch/wizard or human): Wizard
Element: Storm

Appearance: Osias is about six feet tall. He has short and straight brown hair with green eyes. He has a fairly average build, but is a bit on the more muscular side. His skin is light with a slight tan colour. He appears to be somewhere in his early twenties. His clothing varies greatly, but it is usually something extravagant, containing expensive clothes and jewelry. When blending in is absolutely essential, he will occasionally forgo this extravagance and dress in something more common for the area. Most often, this means a hoodie with jeans.

What abilities does your character have: Osias can create storms at will. While this power is impractical for use in combat due to the amount of time it takes to gather clouds and create a storm large enough to do damage, given an hour, Osias could create a storm large enough to knock down trees and damage buildings. This storm would be confined to a small area though, and Osias himself must be somewhere within the area (although not necessarily near its center), or it will begin to lose energy and eventually disperse. He can also cause lightning to strike a location, but there must first be sufficient cloud cover, and on a clear day, it can take him several minutes to create enough clouds. his only other ability that could be used as a weapon is creating sudden gusts of powerful winds, but without first creating a storm, the winds will only last for a few seconds.

Personality: Osias He came into being ((Are mage’s born similarly to humans, or are they created?)) In the early days of modern humans. He has always been fascinated by them, and enjoys manipulating them for no reason other than his own amusement. As complex societies began to come into being, several times he worked his way into positions of leadership. What Osias loves more than anything is power. He thinks himself as above other mages, even knowing that there are ones older and more powerful than him. He rarely goes out of his way to interact with other mages, only doing so when they come to him, or for matters of extreme importance. Rather than wisdom, only arrogance has come to him with the years. Having lived through most of human existence, he has come to hate today's society, and his interest in humans has become increasingly sadistic.
