The red light(stone)

The red light is a stone indigenous to the planet Tark. It came to Earth in 1995 through a meteorite. The stone is wine red in colour on normal times. It has the unique chararcteristic of producing light when in contact with water, turning the colour of the stone to a bright vivid red. The light of the red light can alter the mind of someone who sees its light. turning them evil, which is nearly inreversible. It is nearly impossible for someone who is shine to feel love. They also have a hard time feeling empathy and remorse and are drawn to power. The only thing that can turn a shined person back is love, which is almost impossible for them.

Sixth book
After the people of Earth discovered the stone's ability to shine, they developped a governmental military known as the Red Light Security Agency, or RLSA for short. At the begining of the twenty first century, the stone was acquired by Jack and released to the public through illegal means. This generated an accidental shining that led into a war known as the Red War. The RLSA had always blamed Jack for the war and spent a lot of effort in capturing him.

First book
In attempt to break out of the RLSA prison, Jack accidentaly got himself shine by crash landing a cargo ship filled with red light inside a lake. He then used the stone to shine the forces of RLSA Earth and lead them to his cause. With the help of the Gasans, he managed to shine more than half of the RLSA troops on Venus and Mercury, but reduced its use in battles after losing most of his Red Light stockpiles in the siege of Venus.

During the battle of Svidomad, the Red Light was unable to use the stone due to the limited visibility and the sub zero temperature that turned all water to ice. When the Red Light forces lost that battle, they had hence lost all the red light they had brought on Mars, so they were not able to use it in the battle of Grenna as well.
