I just realized I could talk to that paragon that floats around the smithy/ enchanter room. The problem is, he assigned me a quest, “Learning about runes,” which basically consists of equipping my character with a rune. I already have five runes equipped, and unequipping runes, and equipping them again (or different runes) doesn’t make the quest go away.
You have to talk to him again with the runes equipped. This was a little confusing for me too because when you do equip 5 runes there is no “Quest Complete” message.
He also commonly walks through walls and for awhile I had no idea why. Then I learned there are secret passages in the castle
