The World Above

"50 years ago, humanity used to roam the streets on the surface, kids playing outside, people travelling around, basking in the sun and the soft cool breeze of summer, that is until the rifts opened, weird creatures started to emerge from the rifts, we barely do anything to them." says Triel as she tells Eclair and Sera the story of how the world came to be, the two sisters are in awe of what they heared, Sera said "what about those knights? they can defeat them right?" Triel said "sadly, knights do not exist 50 years ago, modern weapons doesn't do anything to them, but one day people started obtaining mana, people started developing ways to use mana to reclaim the surface, but we still lack resources to do so" Eclair gasps and said "Mana came to be after we the civilization moved underground?" "you are indeed correct, you see mana came to be 2 years after we everyone moved to the underground" Says Victor as he walks towards the three, "excuse me for a moment Triel, i believe it's time for the sisters to do their training" says Victor as he bowed his head, "Ah, It's that time already? very well then, we'll continue where we left off next time" says Triel as she smiles at the two kids, the two bowed and then left with a smile on their faces. after exiting the room Victor explains that they will need to learn offensive magic, he two sisters eyes sparkled and say "Really!?" Victor said with a grin "sadly you won't be casting offensive magic, but rather learn the basics of the formula and -" he was cutted off by the two sisters sighing loudly. "believe me, it is a necessary to learn the basics for it will be useful in the long run"
