Having a powerful follower was certainly gratifying, but Liszt valued a follower's character even more.
Someone like Yevich, who had repeatedly fallen out with his lord and now was willing to defect to invaders over a bit of ransom, had utterly wretched character.
On Earth, he would have been the likes of Lü Bu, the thrall of three surnames—though Lü Bu had at least been the greatest martial general of his age. Yevich was not particularly powerful even among Sword Saints, so the gap between their respective strengths in their own eras was enormous. Still, Yevich had not killed his father for glory; at most, he had fallen out with his lord.
Lords and followers who fell out over private conflicts were not uncommon.
If it were merely a question of character, accepting his allegiance would not be a problem. Even the most despicable person would have to obediently accept his assignment under Liszt. Otherwise, Liszt's Sky-Slaying Greatsword would show no mercy. Dragon or snake, in his territory, all had to coil up.
What concerned him was resources. Once Yevich followed him, before receiving a fief, Yevich's potion consumption would certainly depend on Liszt.
