The Devilbane Saga (en Inglés) - Michael D Stansbury

His family hunts devils. Now the devils have come for a whole city.

Nitox Devilbane was done with the family trade. For seven quiet years he kept a cabin in Oakenrest and a stool at the tavern, among people who never knew his name. Then a letter arrives from Nymdath, the thief who taught him everything he knows. There’s a job in Platnis, and Nymdath would rather have Nitox at his side than anyone else he could hire.

So, of course, he goes.

Platnis, the city built on platinum, is rotting from within. Its mines have been sealed for a hundred years, and whatever killed the miners is climbing toward the surface. The captain of the guard offers a desperate bargain to a band of strangers: clear the mines, and keep whatever you find.

Beneath the mountain, Nitox and his unlikely companions find something far worse than monsters. With him are a sharp-tongued druid with secrets of her own, a paladin led there by a dream, a stubborn dwarf, a hopeful bard and a gnome who never stops talking. Something down there has been digging a door, and on the other side a demon prince is waiting. Someone in Platnis’s own halls of power has been holding the key.

By the time Nitox finds his old friend’s last warning, "Don’t come to Platnis," he is far too deep to turn back. He carries a sword that speaks in his mind and that he isn’t sure he can trust, and his friends are falling in the dark. Before the dead rise and Platnis falls, Nitox must learn what the Devilbane name really means.

The Fall of Platnis is a sweeping, darkly funny epic fantasy of cursed mines, ancient evil and hard-won friendship, for readers who love classic sword-and-sorcery adventure.
