This story is dropped. I'm sorry.

In short: Weak to strong, but there's always someone stronger. Wholesome twins try to navigate a cruel and selfish world.

Secluded on a border world and selected for their talent in fire mana, the siblings are unknowing participants of a centuries-long experiment, hosted by a powerful eccentric on the verge of immortality. Follow the twins as they learn of and attempt to escape their predicament, before venturing out into the wider world(s).
