Dungeon Defense - Chapter 1: Prologue

Cassian had lived his life in the most miserable way. He had scrubbed the floors and washed the clothes in the cold winter and done everything just to please his uncle’s family, but in return, they sold him to a merchant only for a pouch of coins.And the merchant decided to gift him to the king of Aetherlyn, a faraway kingdom from his small village to show his loyalty and curry favor from the king. And he was the lucky one from the group to be choosen by the king. Thus he got the position of palace servant.Cassian thought maybe his life in the palace would be different, but he was bound to be disappointed as the people in the palace were far more sinister and ruthless. Scheming ran in their blood.And can anyone tell him why his path always crossed with the notorious first prince of the kingdom? The seemingly cold prince had an unpredictable temper. And why was he always drawn to him like a moth to a light?Will Cassian be able to survive in the palace where the true faces are hidden behind masks, or will he become more entangled in their schemes and just become a mere pawn in their game?

July, 1946. The existence of an alternate world was confirmed.

It was supposed to be a new world for mankind.

However, the enormous cost, the annihilation of the advance troops, and fierce public opposition led to the signing of a non-aggression treaty.

Mankind turned their eyes towards space.

Half a century later.

A certain company formed a team in order to explore the alternate world’s dungeon.

Five professionals and three artificial intelligences. And one reserve member.

With modern weapons and technology, the adventure was expected to be easy.

However, the ones who had arrived in the alternate world were a defective artificial intelligence and a non-professional.

Through trial and error, they lived, ate, and fought. And, they explored the dungeon.
