In my former life, I dedicated most of my adult life to achieving my goal of exploring the stars. Unfortunately, due to circumstances outside my control, my life abruptly ended leaving my dream unfulfilled. Thanks to the intervention of the Big Guy Upstairs, I was given a chance to achieve my dream though the one who reincarnated me screwed me over. Unlike the futuristic type of world I wanted to start in, I ended up being born in a medieval, magical world as the third son of a regional baron. All I can do now is Dungeon Crawl for ancient technology in the hopes that I find a ship or technology to get me off this damn world!
