The Fiery Scion

You play as a young mage just getting out after over a decade of confinement. Powerful, but raw, he needs to learn to tame his Flame, a powerful elemental magic that he inherited from his absentee father. You will follow him as he recruits his party, goes on adventures, make friends and lovers, and populates his harem. And, more importantly, gets all his women pregnant! But danger loom over the world...demons from another plane try to invade, again and again. Last time, they were repelled by a group of Heroes, led by the main character teacher, at a great price. Now, decades later, they threaten the world again.
