Thousands of years ago, in an unfamiliar land, extraterrestrials constructed a time portal. The inhabitants of that land ventured into our world by discovering this portal. Upon passing through it, some underwent transformations, becoming unnatural beings, while others assimilated into our society. However, their objective is to conquer our world entirely! Hence, we implore you to join us in the battle against the Mulleans. ( We will equip you with everything you require )
