Probably create the story/universe I have bottled up in my head, which is basically an alternate Earth with different landscapes, countries, and history, as well as give life to some of my characters. At first it will be in a past setting, with swords, magic, and bows and arrows reigning supreme. There would be a few monsters, demons, and other rare things like elves and mermaids and such, but for the most part humans are the dominant species. There'd be a few kingdoms that are divided by their different ruling families, each with their own way of ruling the land, and their own technological advances. One would be a fair ruling kingdom with a strong military. Another would be a peace-seeking one that specializes in magic. Yet another focuses on more technological innovations like steam, firearms, and even electricity. This setting would focus on 5 characters in particular: 1) A young prince skilled with a great sword, he is loyal to his kingdom to the end, and would do anything to protect it. But he's also rather power-hungry, willing to do anything to become stronger, if it means to protect the ones he loves. 2) A hulking demonic guardian that is tasked with protecting the prince's life, not allowed to die or rest so that he may stay on top of his task. Despite his fierce appearance, he can be rather friendly, so long as no one threatens the one he watches over. He wields a massive axe, using his brute strength to smash his enemies. 3) The prince's best friend and sworn brother, a young man that is trained in both martial arts and magic, combining the two to become a force to be reckoned with. His missing eye, covered by an odd eye-patch, as well as his exotic accessories and strange mannerism hints that he has quite a history, and perhaps doesn't belong in this time. 4) A young princess hailing from a nearby kingdom, she is gifted with healing and enchanting magic, able to help her allies in times of need. She has a habit of leaving her kingdom unannounced to go on adventures with her friends, at times utterly ignoring her status as a princess. 5) A young woman hailing from the same kingdom as the prince, she was orphaned as a child and learned how to become a thief by growing up in the streets, sometimes fighting just to survive. Her ability to remain undetected is near impeccable, and has trained herself to use daggers as weapons, as well as a crossbow that she has held onto since she was a child. She doesn't become involved with the the other 4 until a fateful event that utterly decimates the entire kingdom, her survival only ensured because she fled to another kingdom to avoid authorities days earlier. Upon her return, she only finds the prince to be alive, standing among the ruins of what once used to be his home castle. Whatever the event was, it traumatized him to the point that he emits very little emotion, and his eyes radiate a ghostly white, hiding whatever window to the soul he has left. These 5 eventually travel together as a mercenary band across the land, helping those in need, with the ulterior goal is finding out what caused the decimation of the kingdom and its people, all the while I shape out their journey and fate.
Knowing my luck though, it'll all just end up looking like some shitty Minecraft world or something once I try creating this world in my image.
