When Kyran turned 18, his life turned upside down. The Royal Army raided his clan because his supposedly non-existent magic got exposed. On that fateful night, he was the only one who escaped. Up to the present, the status of his clan was unknown. A magic inheritance that became a curse, Kyran became a fugitive. Always on the run... living in fear when the Royal Army finally captures him. At least that's what most people thought... "I'll definitely save my family. And I will make all those who made my clan suffer pay tenfold. I'll make use of this magic they so feared, and show them what real terror is...." Disclaimer: The cover image isn't mine. I'll replace it when I finished mine.
Dimension is a magic construction far more potent than a Magus's Domain. It allows a mage to create a secondary layer around a targeted area and gain control over it. Anything that enters that Dimension will be subjected to the mercy of the mage that created it. Even a Sovereign-level mage would be unable to do a thing once trapped inside.
Nevertheless, Dimensions are not a sure-hit skill. For one thing, one needs time to cast it. From this, if another disrupts the casting of a Dimension, then it can be broken. Of course, it will depend on how the other party disrupts it. The most effective way is to directly attack the caster or counter it by casting another Dimension. However, once a Dimension is completed, the only way to counter it is if another mage successfully attacks it from the outside. Putting a crack in the Dimension veil can allow those trapped inside to escape.
