Ask around Morthal and the player may uncover a vampire plot.

It is the stories and experiences found along the way. The player will need to complete a few quests around the hold, but the main reward isn’t really the Thane title itself. This will grant the Dragonborn access to a new weapon to serve as a badge of office, the privilege to buy property in certain holds, and the ability to have the guards turn away from a crime once. Each Jarl in the province is allowed to grant the player the title of Thane if they gain enough of a positive reputation in their hold.

Being the Dragonborn who defeated Alduin is all well and good, but what if the player wants their character to have even more prestige? To have another title.
