Wyrmstooth is an expansion-sized mod for Skyrim that takes you to the island of Wyrmstooth located north of Solitude. Basically, you are given a quest which involves battling across new landscapes and through various dungeons.

Start quest

Your journey begins after the East Empire Company employs you to slay a dragon that is interrupting sea trade throughout Skyrim. By default, Wyrmstooth storyline begins once you have reached level ten or above and have completed Way of the Voice quest. If these conditions are met, you will be tracked by an Imperial Courier who travels on foot to your current location to deliver a message.

Gameplay

The core experience involved grouping up with a team of mercenaries to fight against monsters through one of the largest dungeons in Tamriel. Your companions react in a dynamic way and help you clear through the hordes of enemies you will be facing along the way.

Besides killing mobs, you can purchase an abandoned imperial fort from Lurius Liore. It is possible to fully furnish your new home, hire staff, and defend it from unwanted visitors. In case you want to use realistic and varied grass textures, you may use another mod for Skyrim called Unbelievable Grass Two.
