Simi is a young resident of Kopakasot, daughter of Vasevero and Kaba. Simisevero Debani Espoti is her formal Rimeos name, her given name meaning "eldest (daughter) of (Va)severo". However she is commonly called Simi ("pebble") by her Gimos-speaking fellow townspeople.

The arrival of Rara Gre Chapu resulted in her mother being ensouled and her father being taken prisoner. She was one of the ambassadors to Rimea with Thera.

Simi's story is told in the Firebird.
