Description
This makes Bryling available as a follower after becoming Thane of Haafingar and completing The Horn of Jurgen Windcaller. If you have also completed either The Wolf Queen Awakened or the Civil War on the Stormcloak side, she becomes available as a marriage candidate.

Her follower and marriage dialog options become available about one in-game day after completing the quest requirements.
 
Her stats are changed as follows:

• Class: CombatWarrior1H (actually unchanged – she is this class in vanilla)
• Combat Style: csHumanBoss1H (heavy armor sword & board, same as Lydia in vanilla)
• Level: 10-50, levels at 1x with the PC
• Status: Essential (unchanged – she is essential in vanilla)
• Health: +50 to make her on par with other standard followers
• Perks: Light Foot, so she doesn’t trigger traps
• Gear: As a stay-at-home spouse she doesn’t need any. As your follower, you’re her rich new sponsor. She needs good heavy armor, a sword and a shield. She’s decent with a bow too. I’m sure Bierand will be happy to supply you with whatever she needs.
  

Her vanilla voice type is one of the standard follower and spouse voices (Female Commander, like Aela, Iona, Rayya and Uthgerd), so she is automatically fully voiced as both a follower and spouse. She will also receive the additional dialog provided for Female Commander by mods like Relationship Dialog Overhaul and Young Lovers.
 
Installation
Uses a FOMOD to choose between:

• A version that should be compatible with all NPC replacers but requires ConsoleUtilsSSE (or ConsoleUtilsSSE-NG).
• A version that uses an ESL-flagged ESP to modify her game data. This version doesn't need ConsoleUtilsSSE, but will likely conflict with appearance replacers.
  

If installed during a save and you have satisfied the requirements for follower or marriage, those dialog options will become available about one in-game day after installation.
 
Uninstallation
It's best not to uninstall during a save. If you are determined to, bring up the console and type help TAJ_FollowerBrylingQuest. Then type completequest <formID> where <formID> is the value shown by the help command; it will be of the form FExyz800 where xyz will be 3 hexadecimal digitis. Then wait 24 hours, save, exit, uninstall.

• Bond of Matrimony: Gives the rings you receive during the vanilla marriage ceremony a unique custom enchantment that effectively gives you and your spouse a shared health pool. ESL flagged. No requirements beyond the base game.
• Todd's Quest Leveling: Adds a level progression to the major questlines, making each successive dungeon in each questline higher level than the previous one. ESL-flagged.
