This is Halder. He's a heavily obscured example of a Meska, which for lack of better terms is a talking bear.
His size is not to be used as a reference for the usual Meska. He is freakishly huge, enough so that he can hoist an industrial wrecking ball on a chain with his own two arms.
In this situation, Halder is going after Edith at an undefined site. AV leaps into action to save her because, though she's absolutely useless, the Matriam Naliae will screw him for the worst if he messes up this simple task.
Halder himself doesn't actually mean death on Edith. However, she and AV are liable to pursue his raiding party, which has left their mountain kingdom to the north in search of slave labor as per their ruler's orders. This path leads them to steal the vast majority of the population of Edith's hometown, which in turn brings her to want AV to join her in saving her friends and family.
Halder doesn't even want to be a vicious slave driver or anything. It's just that his midlife crisis has led him to try making a living with the kingdom of the Kalti Meska, and this citizenship has put him in this position. Really, he'd like to settle down with a nice job in the boonies where nobody will bother him. What he'll soon learn is that everybody, for one reason or another, is out to do just that.
He's not stupid. He's a perfectly functional member of society once you get past the fact that he's the size of some houses. Really, he's almost cunning. The constant tendency of his antagonists to overlook this characteristic annoys him too much for him to take advantage of it.
