The world Aresima lives in is one filled with magic and monsters. Humanity, the people of the land, are hardly a footnote in the world's history due to their struggles against nature keeping them in a stagnant state. When dragons are as common as birds and can crush cities with a breath, and the average human is equipped with only a sharp metal stick and mayhaps a little magic, what are they to do?

Humanity has maintained civilization for hundreds of thousands of years, but never reached beyond the technological advancement of what many would consider "medieval." Where technology has struggled, magic has thrived. Those humans rarely born or having acquired a Mana Source experience longer lives proportional to their development of that Source. This means that over many long years, magical advancement has reached high pinnacles. Magical tools are fairly common, if not overtly powerful. Great mages who can move mountains, cut down forests with a single swipe of a blade, have honed and passed down their power for generations.

Outside humanity's walls, nature thrives. Dragons thunder across the sky, flickering will-o-the-wisps and fairies dot the forests with bright colors, creatures of fantastical shapes exist in every corner of the world. Plants that create waterfalls, islands that glide above the clouds, mountains that walk across the land. Truly the world is full of wonders to inspire awe and terror in equal measure.
