Story Emergency...emergency...this is the commander of the spaceship Daria. A major catastrophe has occurred... Having detected an alien distress signal, the Main Mission staff listens to the sombre appeal. The voice of the alien commander tells how large areas of his ship are devastated, with thousands dead and hundreds sick and dying.

Their investigation is interrupted when two tattered dwarves emerge from the hidden passage. Male and female, they are mute and panicked. The male hides in the Eagle while the female attempts to communicate using frantic gestures. The
