Call from Another World: the Demonic Swordsman Rising from the Ashes Forest

[Sword and magic + different world + adventure + big world view + no system + single female protagonist] Lore was inexplicably summoned to a world of swords and magic, and became a "defective" (brave) whose age had shrunk and had no traces of magic. Good news: I was picked up by adventurers from a border town and survived. Bad news: Buried in the deep ash forest next to the town are the remains of a war thousands of years ago, hiding a horror that could destroy the continent. I originally wanted to live a stable life as an adventurer, but I had no choice but to embark on the path of becoming a god by exploring ancient ruins.
