Avalon's Tower, the world's greatest MMORPG.

After transmigrating into a vampire necromancer, I chose to help the protagonist's party.

My reward?

Betrayal.

Deceived by their lies, I was bound in chains and sealed in the deepest floor of a lightless labyrinth.

For a thousand years, I endured nothing but rage and resentment.

Then, on the thousandth year...

The seal was finally broken.

Now, only one thing remains in my heart—

Revenge.
