Dungeon Tamer : Phantom sovereign

After saving the world alongside the legendary Monster Tamer  Goran and eradicating the darkness from the World Tree, Marcus thought he had found peace. But for a boy forged in shadows and raised on the adrenaline of battle, tranquility soon feels like a prison. Especially when he has to deal with an unrequited love that still burns inside him.

Unable to sit still, Marcus sets sail for Eryndor, an exotic and untamed continent, with a new goal: the Great Tournament. The grand prize is exclusive access to the mysterious Sky Dungeon, a cyclopean spire that pierces the clouds, entirely disconnected from the rest of the world and the roots of Ythril. Legend has it that at its peak lies the Celestial Continent, a suspended land ruled by divine beasts.

Alone, but accompanied by his loyal and lethal Shadow Guardian Goblin, Marcus must start from scratch. Downgraded by harsh local bureaucracy and forced to fight his way through mercenary gangs and ruthless monsters, the young ninja must prove to the entire world that he is no longer living in anyone's shadow.

The Phantom Sovereign has arrived. And the sky has never been closer.

What to expect:

Fast-Paced Action & Tournament Arc: Brutal, high-stakes fights, stealth ninja techniques, and tactical combat against mercenaries and monsters.

Light LitRPG / System Elements: Clear class progressions (Phantom Sovereign), distinct skills, ranks (A to S), and currency (Lumen), without overwhelming walls of stat blocks.

A Cocky, Competent Protagonist: Marcus is a confident, somewhat arrogant rogue who relies on shadows and strategy, but is fiercely loyal to his goals. No whiny or weak MC here.

Unique Familiar Mechanics: A badass, spiked-club-wielding Grade 3 Shadow Goblin that fights seamlessly from the protagonist's shadow.

Epic Progression Goal: The ultimate prize is the legendary Sky Dungeon, promising mysteries, divine beasts, and an uncharted Celestial Continent.
