After listening to Stahl's suggestions, the rather disgruntled Sigurd executed them just as the young man had explained after the Core Guardian was asked to do so by Eisen. The old man hoped that Sigurd would end up warming up to other people, although that seemed to be quite far away, and Eisen didn't want to 'Force' Sigurd to be all buddy-buddy with Stahl either, because that wouldn't help the situation in any way.
So instead, all of Stahl's ideas had to be voiced by Eisen, Evalia or Xenia. Eisen had considered turning Stahl into a Dungeon administrator as well, but it seemed like he hit the limit of everything in that area, so instead, Eisen turned Stahl into a Dungeon Moderator. He wouldn't be able to make any major decisions himself, but he would at the very least be able to manually change parts of the dungeon.
Sadly, though, it seemed like Sigurd's opinion of Stahl hadn't been elevated all that much, but it at the very least didn't glare at him all the time.
