Prologue

In the vast and mysterious universe of Orion, there exists nine realms that are connected by the mighty ash tree, Yggdrasil. These realms are Asgard, Alfheim, Jotunheim, Midgard, Muspelheim, Nidavellir, Niflheim, Svartalfheim, and Vanaheim. Each realm is home to different beings and creatures, with their own unique characteristics and powers. However, these realms are not isolated from each other, as Yggdrasil acts as a bridge that connects them all. This tree is said to be the source of life and stability in the universe, holding all the realms together. At the top of Yggdrasil lies Asgard, the home of the powerful gods and goddesses who rule over all the other realms. Led by All Father Odin, these divine beings oversee the balance and order of the universe. As we gaze upon the vastness of Orion, we are reminded of these nine interconnected realms and their rulers, who continue to shape and protect the universe with their wisdom and strength.

Under the rule of Odin, peace reigned over every realm. However, this tranquility was suddenly shattered when mysterious towers began to appear in each realm without any explanation. The gods themselves disappeared, leaving the people confused and scared. As these towers brought forth a seemingly endless stream of powerful monsters, the first monster outbreak in history had begun. Despite their efforts to fight back, the people were no match for the continuously spawning monsters. Even the gods seemed to have abandoned them, as their prayers went unanswered. Just when all hope seemed lost, a new system emerged, granting the people a chance to fight back against the ever-growing threat of the towers and their monsters. No one knew where this system came from, but it marked the beginning of a new era - an era dominated by these mysterious towers. How long this era would last and what challenges it would bring, no one could predict. The people could only hope that with this new system, they would finally have a chance to overcome the tower's power and reclaim their once peaceful existence.
