After players discovered the hidden realm of McGuire's Tomb of Death, it also appeared on the list of hidden realms available to players, and it was one of the advanced hidden realms.
This meant that the challenge level of McGuire's Tomb of Death was above level 100. It was the kind of dungeon hidden realm that players were only qualified to tackle in teams after breaking through to Gold-level.
Of course, some players refused to believe it and immediately assembled a group of top experts to raid the hidden realm.
The result was obvious: they were wiped out to the last man. Even professional players were no exception!
According to information posted on the forums by participating players, McGuire's Tomb of Death was actually a labyrinth deep underground. The environment was harsh, gloomy, and terrifying. Most of the monsters wandering the tomb were zombies, ghouls, and Skeleton Soldiers, with challenge levels between LV110 and LV120. They had fallen before they even saw the final BOSS.
Only after reaching Gold-level, enduring countless hardships and countless party wipes, did the players finally conquer McGuire's Tomb of Death.
The difficulty of this hidden realm was simply absurdly high.
The monsters wandering the labyrinth were manageable. Though their challenge levels were high, they were all mindless undead creatures and generally appeared alone, so they were not difficult to deal with.
But the BOSSes of this hidden realm were a different story. There were three in total.
They were the LV130 Headless Knight Larentz, the LV150 Vampire Angela, and the LV170 final BOSS, Lich McGuire.
Liches had mostly been mages when they were still human. Influenced by darkness and Undead Energy, they were transformed after death into undead with magical abilities.
Some liches were transformed only after death. These liches had practiced necromancy in life
