Lydia Truscan

 is the only heir to the Truscan Family Trust and the daughter of Sydnock Truscan. Howaardt Darrington intended to marry Taryon to her so he could fix the Darrington family's financial problems. Taryon refused and Vox Machina found another way to help the Darrington family.

Lydia was described by Maryanne Darrington as very nice, very pretty, and a bit bookish.

By the time of the Second Campaign, Lydia was estranged from her father and living in Zadash as an advocate for civilian rights.
