—Seteth and Lady Rhea
Rhea and Seteth give Byleth the mission to take down some thieves in Kingdom territory. They have stolen the Lance of Ruin which is a powerful hero's relic. These thieves are led by Miklan who is a disowned son of House Gautier. Because Byleth wields the Sword of the Creator, the pair are confident in sending them and their students to appose them.
When reporting to Rhea, she calls it divine punishment from the goddess. In the library, Byleth and their house leader run into Tomas while talking about how Miklan couldn't use the lance because he lacked a crest. Tomas then talks about how the hero's relics turned Nemesis and the other humans made transforming them into black beasts.
