If the Dragonborn has one of the Aetherium items (Aetherium Crown, Shield or Staff) in his or her inventory, Taron will ask how this item was obtained. He will attack no matter which option is chosen in the dialogue.
If the Dragonborn has no Aetherium items, Taron does not ask about them, but if dialogue is engaged with him he may be asked who he is and told that Katria had mentioned him. He will respond with "You know too much," and attacks the Dragonborn with his three mercenaries.
- He shares his last name with Romlyn Dreth and his possible ancestor Valen Dreth though it's unknown if he's related to either of them.
