NPC: Artificer Morphalius
ID: 19670

NPC: Mamdy the "Ologist"
ID: 19669

These two sometimes have a very short conversation:

Artificer Morphalius says: Look at me! You said I would be fine! Do I look fine?
Mamdy the "Ologist" says: I can only show you the door, Morphalius. You're the one that has to walk through it.
