Days as a Spiritual Mentor in American Comics - Chapter 18 - 12: The Genius of Stacking Buffs_1

In a mass ambush at the Battle of the Gods, the four major guilds with all their armies surrounded one man alone: McRae, known by all players as the God of War.

But even the God of War could not survive alone against hundreds of attackers.

With all his previous memories, McRae knew that their entire world would soon merge with the game world, where death would become permanent… And so he turned on Divine Domain once more– this time fully aware of every detail about the players, the treasures, and the game itself.

Before the four guilds were even formed, McRae would have a guild and an army of his own.
