Ragnarok Online Gamer System

A man appears in a room, without many memories and without a name due to a system error and to compensate a little for the problems that caused him, he receives an "old" version of the gamer system. Little by little he recovers his memories and begins to discover that the small error of which he was the victim is nothing more than the beginning of a disaster. - The system is based on the game Ragnarok Online, a small part of the story takes place in the game but it will focus more on the worlds where the MC will enter. _____________________________________ This is my first story, also English is not my first language so any problem that exists I will appreciate if you mention it.
