Ancient vows have rotted away; the modern era belongs to magic circles.
About
In this world, there are tools that support the use of magic. These are "Magic Circles." A magic circle is formed by drawing a circular formula in the air with mana and channeling magic power through it. It is not exactly simple, but it carries no debuffs or physical strain... it was the optimal method. For those of the modern era. ───────────────────── Long ago, magic was not supported by magic circles. It was done through "Binding Vows," a system where one accepts a burden in exchange for an effect. Magic was sustained through these contracts. However, that is now a thing of the past... ───────────────────── About Ancient Binding Vows: These are techniques that stack restrictions upon oneself, others, or objects to gain buffs or support the activation of magic. However, Binding Vows are now an archaic art. In the past, activating magic was unstable. Binding Vows were born to support and ease that activation. "In exchange for a restriction that makes magic easier to trigger, one's mana consumption is doubled." This is a simple example of a Binding Vow in use. The applications are infinite. However, they are cumbersome, as they always impose a debuff on the user in exchange for various effects and buffs. The reason they fell out of use is simple. Nowadays, "Magic Circles" are used to support magic instead of "Binding Vows." Magic circles allow for activation by drawing a formula in the air and channeling mana. Because these circles carry no debuffs, they became the standard in modern magical society. Binding Vows were born approximately 2,000 years ago. Magic circles were created 1,000 years ago, causing Binding Vows to fade and eventually vanish. Today, no one knows of them anymore. There is only one person left who uses this art. Yaon...

Sourcebook
Intro
In this world, magic is unstable. Attempting to use it raw usually results in a backfire or a total failure to activate. However, by using techniques that support the casting process, magic became usable.
Approximately 2,000 years ago. This was the beginning. A technique created through research into the stabilization of magic.
Binding Vows
The people of 2,000 years ago created Binding Vows, enabling the use of magic through them. Even though it imposed a burden on the user, it was better than not being able to cast at all. That was the mindset of the people back then.
900 years passed.
