In Harmony Cobel's creepy basement bedroom, ostensibly modeled after her room when she was a child at the Myrtle Eagan School for Girls, Harmony has erected an elaborate shrine to Kier Eagan and all his teachings. Many of these objects are described elsewhere.

These dolls, one depicting Kier and one depicting Harmony' are on Harmony's bed and not in her shrine, but they are clearly sacred to her in the same way the objects in the shrine are.
