The setting for the fourth of the Legend of Heroes and the first in the Gagharv Trilogy takes place in the fictional land El Phildin, fifty-six years before "Moonlight Witch". The story begins with an insight to the past. Avin and Eimelle are orphaned children living in Cathedral. Avin was 8 while Eimelle was 7. Avin retrieves milk for the cat Eimelle brought into the chapel. They both watch the kitten drink to its content. Before long, Oracle Ollesia yells at them to take cover. Cathedral is under attack.
Lord Belias and his minions attack the chapel. He is after Eimelle who he calls "Durga's Daughter." He is stopped by High Priest Esperius. Both have a conversation of how Belias used to be destined to lead the Bardus Church someday and how Belias became traitorous. The two wizards fight each other. Esperius dies after being attacked with a rising spell.
The two kids and their oracle attempt an escape before being captured by Belias. Gawain, the "Sage of power," fights to fend off the attack. The rest make an exit to the monster cart. The cat screeches after hearing the spell cast. Avin tried to rescue the cat, but is left in Gawain's care. Ollesia and Eimelle escape to another place.
