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.
Although Gage couldn't survive an attack from a magical beast, this was only based on the assumption that he was still a Master mage.
However, considering what Cyneah said before, when beasts chased her, and Gage managed to kill one by himself, Kyran had to reassess his initial thoughts.
Cyneah might not have specifically said what type of beasts had chased her, but considering they had relentlessly pursued her, with one even going so far as coming after her when she fell down a gorge, they were all feral.
If that was the case, for Gage to have killed one meant his combat and magic prowess was already way beyond a Master.
For the record, the lowest mage level Kyran encountered in Somuli was at Grand Master. Hilam and his team were at that level. As for most of the Eidums defending the borders, they were Exalteds.
