— Isolde Valen

Isolde Valen is a refugee being held within the Hall of Columns in 2277.


The daughter of a Talon Company mercenary, Isolde lived a life of moderate luxury and innocence, being hidden away from the rest of the problems plaguing the wasteland around her. Isolde developed Hemophilia later in her life, which had led to her father Gerrard being over-protective of her well-being, and tried to be the best father he could be since her mother died years before.

Eventually, Isolde caught the eye of the leader of the Talon Company, Commandant Aix, and he began keeping tabs on her and her father. Aix, while planning a contract that would lead to Gerrard's death so he could take Isolde for himself, immediately became aware of Gerrard's plan to escape from the Capital Wasteland. Isolde was kidnapped by Talon Company mercs, and an assassination squad was sent in to deal with her father.

Now, Isolde spends her days being held at a laboratory within the Halls of Columns in the Capitol building. Should she be rescued from her prison, she will express that she yearns for freedom, and for the chance to finally learn of the world around her. And while she might be in a delicate state due to her condition, her medicine and repair skills learned from years of confinement will be of great aid.

Other interactions

  • As long as Isolde is a companion, she will give the Lone Wanderer the Guardian Angel perk. (Needs to be unlocked first)
  • Isolde Valen has a unique script only shared with Gerrard Valen. At night time, should the party be outside, Isolde Valen will offer to set up a campsite. Sitting at the campsite, the option to sleep and the option to talk will be presented. Should the sleep option be taken, the party will awaken again at 7 a.m. Should it be chosen to talk, Isolde will discuss the day, such as if the party was ambushed by raiders, or attacked by a deathclaw, etc.
  • Isolde has the ability to heal, cure addictions, and even fix crippled limbs, so long as the appropriate items are in her inventory. With a Medicine skill at 100, Isolde is very effective.
    • Isolde also has the ability to repair any weapons and armor, so long as she is supplied with scrap metal and other parts such as wonderglue.


  • Even with her condition, Isolde is still handy with Small Guns, and can handle herself in a firefight. However, due to her low health, she shouldn't be left to deal with enemies by herself. With Misha as a loyal companion, Isolde's combat capabilities are improved further.
