When first entering Understone Keep, Thongvor is seen arguing with Brother Verulus, demanding to see his deceased ancestors, but being denied entry to the Hall of the Dead due to unusual reasons, inevitably leading to him accusing Verulus of being an Imperial supporter. Upon talking to Thongvor, he quickly demands the player to answer whether or not they are loyal to the Empire or supportive of the Stormcloak rebellion. Regardless of the answer, Thongvor will reveal that he is a strong Stormcloak supporter by telling you that the Imperials have no place being in Markarth and angrily exclaims that Jarl Igmund is a puppet to the Imperial government. He even explains that had it not been for Ulfric Stormcloak and his Thu'um, Markarth would have still been under the control of the Forsworn, prior to settlement.
If the Stormcloaks take the Reach, Thongvor will replace Igmund as Jarl. When Markarth is under his control, unlike Jarl Igmund, who uses caution when dealing with the Forsworn, Thongvor reveals that his intention as Jarl is to violently suppress and enslave the rebelling dissidents by sending them to Cidhna Mine as reparation for the rebellion. If the Empire retakes the Reach later, Thongvor will spend the rest of the game at the Palace of the Kings in Windhelm.
In a cut part of the Imperial Legion questline, there was going to be a siege of Markarth in the event that you had lost the city in either a battle or as a result of Season Unending. This siege would play out almost exactly the same way that the Stormcloak variation of the Battle for Whiterun does in the main game. Upon reaching the throne room, you would be greeted to this exchange (note that this is the same dialogue that would play between Maul and Jarl Maven Black-Briar if you were taking the city of Riften back for the Stormcloaks under the same circumstances):
|Yngvar:||"Halt in the name of the Jarl!"|
|Thongvor:||"Somehow I doubt that will persuade them."|
|Yngvar:||"Stay back, lord!"|
|Thongvor:||"If they want my city, they're going to have to take it from me personally."|
|Yngvar:||"Protect the Jarl with your lives!"|
Once the ensuing battle had ended, this exchange would play (Again, this is the same dialogue that would play if you were taking the city of Riften back for the Stormcloaks under the same circumstances):
|Igmund:||"Ahhh... It's good to be home."|
|Thongvor:||"Welcome back. I've left a few surprises for you to discover."|
|Igmund:||"How kind of you. And I've brought an army to give you a going away parade."|
|Rikke:||"If you two are finished with the touching homecoming, there's a city in chaos out there."|
|Igmund:||"Indeed. Come, there is much to be done."|
If you were taking the city for the Stormcloaks however, the battle would conclude with this exchange between Igmund, Thongvor, and Galmar:
|Thongvor:||"Ready to listen to the Silver-Blood family now, Igmund?"|
|Igmund:||"Thongvor. I should have executed your whole treacherous clan when I had the chance."|
|Thongvor:||"Don't worry. We'll take good care of your city when you're gone. When Ulfric Stormcloak becomes High King, Skyrim will finally be the way my ancestors intended. It's a new day in Markarth."|
|Galmar:||"Are you two quite done? You, go pack your things. And you, go sit on that damn chair and start acting like a Jarl."|
|Thongvor:||"Come Galmar, we have much to do."|
|Igmund:||"The Empire will return. Count on it."|
- Bad scripting in his AI packages causes Thongvor to spend all his time in Understone Keep, instead of taking meals, sleeping in the Treasury House and visiting Ghorza gra-Bagol.
- This bug is fixed by version 1.2.7 of the Unofficial Skyrim Patch.
- When discussing his hatred of elves due to the White-Gold Concordat, Thongvor will not refer to you as an elf if you are an elven vampire.
- He is set to visit Ghorza, even though he only has conversations available for her brother, Moth, who he never meets.
