The creation is fully voiced using lines from the base game spliced together, and even includes new scenes made specifically for the expansion.
Now, they’ve launched a mod that “expands Molag Bal’s daedric quest, giving you the option of choosing an alternative ‘good guy’ route to finish the vanilla quest”.
Prolific modder JaySerpa has previously created a bunch of impressive Skyrim mods that add more immersive interactions, a fully voiced, expanded overhaul of the famous Paarthurnax quest, and even the ability pet Skyrim’s doggos. The decisions you have to make might not sit so well with those Dragonborn determined to take a more virtuous path through their adventures, but the good news is there’s now a “good guy” route available thanks to a quest expansion mod. You head into a house tormented by Daedric forces in the stone city of Markarth, and you have to take some, well, pretty tough actions to resolve the problem. House of Horrors is a relatively minor Skyrim quest, but a memorable one.
