Unfortunately, in the vanilla version of Skyrim, it is not possible to marry a cured Serana or any other vampire for that matter. This limitation is present in the base game and cannot be changed without the use of mods. As an AI language model, I don’t have personal experiences, but I can provide you with information about the game mechanics and options available to players.
In the Dawnguard DLC for Skyrim, players have the opportunity to interact with Serana, a unique and complex character who happens to be a vampire. Throughout the DLC questline, players can develop a close relationship with Serana, but the game does not offer an option to marry her even after she is cured of vampirism.
However, it is worth noting that there are mods available for Skyrim that allow players to marry Serana after she is cured. These mods add new dialogue options and relationship mechanics to the game, enabling players to take their relationship with Serana to the next level. Modding can provide a more personalized experience and allow players to explore different possibilities within the game.
If you are playing Skyrim on PC, you can browse popular modding platforms like Nexus Mods to find mods that enable marriage with Serana or other vampires. These mods often come with their own set of requirements and installation instructions, so make sure to read through the mod description and follow the provided guidelines to ensure a smooth experience.
While it is not possible to marry a cured Serana in the base version of Skyrim, mods can offer a solution for players who wish to pursue a romantic relationship with her. Modding can enhance your Skyrim experience by providing additional content and customization options that cater to your specific preferences.
