Twilight Memoria: Sun and Moon is an RPG set in a fantasy world full of monsters, following two children from a peripheral village. Rucifar Demien is the son of a famous local adventurer — a fighter type, physically capable but not academically inclined. Luna Silver is a prodigy in alchemy — brilliant but physically fragile. Their strengths and weaknesses invert each other precisely: what one is good at is what the other struggles with. Together they take on requests gathered by the village chief and spend their time teaching each other to fill the gaps the other leaves. They are just kids from a small village, but they are not idle ones.
