Siegfried loves to set feathered damsels free. Because he likes to receive a "reward" from them maybe... But in this case, for his adventure, he needs a healer, whom he could not hire in the city. But luck smiled to Siegfried and he was able to save the pigeon priestess from trouble (she was captured by a small gang of rats) right on the way. I think that her help will be very useful in a long and dangerous journey.
