Random question from the latest episode
Not sure if this is only phrased this way in the anime, but saying the dungeon "appeared" in Tempest makes it sound like they either don't know and/or don't care that Ramiris actually created it after Rimaru asked he to.
Do dungeons/labyrinths actually appear spontaneously in this world, or are they just being greedy and stupid because of Mariabell's control?
