In this world, monsters were classified by their danger levels.
Their ranks ranged from 5 to 1, with Rank 5 being the lowest — though "low" was relative.
A single Rank 5 monster could be extremely dangerous to an untrained civilian.
A horde of Rank 5 goblins, moving with feral coordination, could even overwhelm and slaughter veteran fighters.
Rank 4 monsters required more than mere skill to handle; they needed precise tactics, specialized weapons, or in some cases, outright magic.
And Rank 1? Those were calamities in flesh — beasts and horrors that required armies, heroes, or both to even wound.
They were monsters that were suspected to be as powerful as gods and there were quite a few of them in this world.
The Shadow Wraith standing before Azel was Rank 4.
That alone was bad enough.
Worse, it was a ghost-type.
Shadow Wraiths were insidious monsters: specter-like entities with thin, humanoid forms that seemed to melt into the air.
