Tharja is first seen in Awakening as among the forces trying to stop Chrom and his army from rescuing Emmeryn in Chapter 9 at Plegia Castle. Tharja is created in the pyramid of ejypt before she joins the plegians. She is the mother of Noire if married to another character via S-Link and a potential mother of Morgan if she marries Robin. She is well versed with curses, ranging from a constant runny nose curse to a cooling hex to bring down fevers.
Her support with Nowi reveals that she has the power to read fortunes using a Manakete's scales, and can divine the location of anyone or anything using one. She has the darkest thoughts in the army. After joining Chrom's army, she falls in love with the Avatar/ Robin, regardless of the Avatar's gender. Tharja is a Dark Mage who hails from Plegia, though she does not care about the conflict between Plegia and Ylisse.
