Bloodwraith thought of himself as an effective villain, until a single adventurer destroyed his entire lair. With his last breath, he switched bodies with the adventurer and discovered that his world was built on lies. Alien beings from another dimension were using his world as a game... and now he was one of them.

The problem is, Bloodwraith has no experience being an adventurer. He was a mage, but his new body is only good at hitting things. He relied on undead minions, but now he has no choice but to depend on other people. And worst of all, strange boxes are constantly appearing in his vision, describing the world in unfamiliar, nonsensical terms.

Taking over the world is off the table, because the alien gods might be watching. To survive, Bloodwraith will need to learn the truth about himself and his world. And that means acting like an adventurer, at least for now.

In a distant world five times the size of planet Earth, dungeons and their dungeon cores have become the top of the food chain.Millions of dungeons inhabit the planet, utilizing the various human kingdoms as a source of much-needed mana to facilitate their own growth; in turn, the humans delve into the dungeons and acquire their own power in the form of Essence, which allows them to develop and enhance themselves in a multitude of different ways. It is a symbiotic relationship that has lasted centuries and has brought about a measure of peace.Far in the northern wilds where no humans (and therefore – no dungeons) regularly frequent, a young man is left alone when his parents are murdered suddenly and unexpectedly. Now, without friends, family, or even supplies, he embarks on a journey to find out who targeted his parents – and who he needs to enact his revenge upon. Along the way, he discovers something about himself that his parents said was impossible from the moment he was born.Will he learn to control the new powers he has gained, or will his newly awakened dungeon core abilities consume him?
