The human of the crew turned pale. “We need to go,” they said urgently. “We need to go right now!”
The rest of the crew’s blood (for those who had blood) ran cold. Humans are from a death planet. If this message could scare a human, it must mean something terrible.
“We shall return to the ship immediately,” said lieutenant O'tek, trusting his human’s intuition. “Quickly,” he added.
The crew hurried back to the exploration pod, the more anxious members of the crew wondering what the significance of this message was. Rae, the human, didn’t explain on the way back, but the Tri'bax'i members of the crew, who had remarkable eyesight, could see the small hairs covering the human’s skin were raised, an instinctual response to danger.
When the exploration pod docked in orbkt, lieutenant O'tek turned to Rae. “You should report this to the captain. Please explain what we saw and why it was dangerous.”
The human was still tense. “No. Everyone who was on world needs to go to medical bay and get checked out. Immediately.”
“Very well. But could you please explain why?”
“That message. It’s an old human message that means danger. Danger you can’t necessarily see. Danger that can affect your health with just one exposure. It was first used for nuclear waste.”
O'tek’s red skin paled until it was almost pink. He had heard of the ‘nuclear wars’ the humans engaged in that nearly destroyed their planet in antiquity. He had heard of bodies being incinerated in a split second and illness that was incredibly painful and had no cure. Such were the horrified whispers about humans in the galaxy.
“Everyone to the medical bay. Now.”
The exploration crew didn’t need to be told twice.
Doc Jones, also a human, was surprised to see ten crew members arrive at once.
“Lieutenant! What can I do for you? What is going on?”
“We saw a sign carved into a rock,” Rae explained when the lieutenant indicated for them to speak. “The nuclear waste message. Nothing else. No life. No animals. Just an empty jungle.”
“Okay, everyone in isolation,” Doc Jones said, quickly mentally assessing the situation. “Lieutenant, get on the comms and explain to the captain that everyone is out of commission for two weeks. I’ll get the scanner ready.”
One by one, the crew members were examined. None showed any signs of anything wrong. The two weeks of isolation didn’t produce any symptoms. But the humans were tense for long after the ship left the mysterious dead planet. Some mysteries are better left unsolved.
