The Regression Of A Grand Mercenary

Fighting all his life due to a promise brought upon by his dying sister's last wish, he lived his entire life all for the sake of that promise.   And through his life, he had gained an unsurmountable amount of fame, being known as the 'Wind Crazed Orc Slayer' and even 'The King of Mercenaries'. Reaching heights that only so few could ever dream of.   With his life as a warrior, finally his time came to an end against a glorious beast known as the Glacial Dragon.  One of the grandest beings to ever live in the realm of mortality. A beast that guards one of the grand ambitions of the world.   On his death, he regretted the lives he took and could only ever take in the reality that he was not a Good person. He only ever survived through the simple promise of his sister's dying breathe. In his nearing death, he started to see certain flashbacks of his past...   But to a sudden development, he had regressed after defeating the Glacial Dragon back to his past life.   And seeing this regression, he felt compelled to finally repay everything that was done wrong to him and his family. As the grand mercenary that he was, nothing will ever come between him and his goal.
