Welcome to the System

For most, the system came out of nowhere, creatures out of fairytale invaded the world, killing and enslaving all they could find, but the government knew... and was prepared.  As the monsters came, the army reacted, turning cities into war zones and survivors into assets, they hoped to keep a semblance of justice into this new world.  Aaron Ross is a member of Ragnarok, one of the many gifted men and women trained from birth to become loyal heroes, to lead the fight when the system came. Unfortunately, he is not the savior they want, instead, he could be the killer they need.  WARNING: This is the second fiction I have ever written and the first I am posting! English is NOT my native language so expect many mistakes, mature tag is mostly for cursing and gore, sex may be included latter DROPPED, I will not be picking this again.
