The Great Cleric: Volume 5 (Light Novel) by Broccoli Lion

With the dragon “slayed” and corruption in the Church uprooted, Luciel returns to Yenice a hero, but a hero’s work is never done. His revolution is ambitious (too ambitious, some might say), and in the wake of change always comes resistance. As it turns out, dragons just might be the least of his worries when he realizes that the weeds he plucked might have only been a symptom of the City of Freedom’s underlying disease. Politics are a dangerous game and Luciel’s found himself stranded on the board, but is he a player or a pawn?

As the Wicked One’s shadow creeps nearer and the empire’s boot marches ever closer, Luciel’s prospects of a peaceful life seem to slip further and further away.
