I'm a Noble on the Brink of Ruin, So I Might as Well Try Mastering Magic: Volume 6

The Duchy of Parta is desperate to make amends for their traitorous transgression. Watching the human nations flounder about is nothing new to Liam, and dealing with them is just business as usual, but there are stars in Liam's eyes the moment he learns about the 'necromantic magic' in their possession-the power to subordinate dead souls! Liam and the Duchy of Parta soon find a quick path to reconciliation, but what could have been a simple diplomatic exchange is soon shrouded in an ominous fog as conspiracy brews in the neighboring duchy. Liam realizes this might be more serious than he thought, especially when he hears that two foreboding words are being passed in hushed voices within the grand duke's abode: 'Dragon Slayer.' Whatever it means, it couldn't be good for him or the three ancient dragons now living in the city!
