The Mourning Undead Soldiers took a sniff of the Deadman's Fruit and then silently slipped it into their pocket, picking another one and then taking off again to patrol the sky.
After a large circle, confirming that the area was 'safe', the Mourning Undead Soldiers flew back, passing another Mourning Undead without a sound, quickly stuffing the new fruit into their hand, then ascending to the airship, standing guard from above.
A hint of surprise flashed through the lifeless eyes of the other Mourning Undead Soldier as they silently held the Deadman's Fruit, and then, while the four wizards were not paying attention, quickly took it out for a quick glance, and soon spotted something, sniffing it intensely beneath their nose before their eyes lit up.
