Short explanation about how it started.
The Eagles were sent to many battles till Red noticed some melites at Luhgreten. She was sent there with Revan and Bob and a few others, including the General, to deal with them. In mean time Lord Kuvio Eirikr were arrested and killed and Cataryna was sure this started the strange sequence of events. She remembered to be so angry with his death that she could not avoid to feel happy when she wounded the melite Judge, Kalixta.
After the last battle at Sandefur she remained trapped in a spell at Winifael for a few turns and several days passed, during which she took orders from Red sent by his scribe, and some in his own hand, letters that she kept carefully amid the breasts until she could finally rejoined her army, the best army of all time, the Eagles of Hope.
