The true origin of the dreaded quartz in the

In part 5 Game of kingship, when Tyrion and Jorah Mormont were sailing through the ruins of Valyria, they were suddenly attacked by the quartz. Both characters were brave but before this scene was extremely panicked.

Tyrion is lucky not to be bitten by the agar but Jorah is at risk of getting sick. It is not without any reason that greyscale (gray scales) - the name of the disease, becomes a horrifying obsession throughout the length of the Game of Kingship.

Once infected, the gray scales will spread to the body, eventually eating into the internal organs and brain, causing the patient to become crazy. People who get sick will die slowly, for a year, 2 years, 5 years, even if there are a few of them live for up to 10 years; But they all gradually become weak, clumsy, sluggish and stupid.

The disease can be easily transmitted through skin contact. As a result, victims were often taken to the ancient city to abandon Valyria but a quarantine form. There was a theory that greyscale was a biological war weapon in the battle against the Valyria.

In Part 1, Prince IIlyrio said that up to 2,000 were killed by greyscale after the disease spread through mice. At the ancient citadel, the government had to burn all the boats to prevent the disease from spreading.

Many royal characters have suffered from this disease. Harlon Greyjoy, Balon's brother was infected but was allowed to live in isolation. Princess Shireen Baratheon is also one of greyscale's victims. She was infected from an imported doll and her father, King Stannis "million all the masters in the world. Every doctor, every pharmacist. They stopped the disease and saved their lives."

However, because the face saved the greyscale traces, Princess Shireen was locked up, separated from the world and eventually burned to death.

Martin is a person who loves history and has relied on many medieval historical events to write his books. However, he never mentioned that greyscale relied on a real illness.

However, when examined carefully, it can be seen that greyscale has many similarities with leprosy . According to dermatologist Anthony M Rossi: "Like greyscale, skin damage in people with leprosy is caused by the diseased skin area . The skin is broken down and sores because the patient does not feel anything. As in the film, long-term illness can cause patients to deform and lose their eyebrows, even losing their ears, nose and toes, hands ".

Although non-infectious leprosy like greyscale but people with illness are often ostracized, both in Westeros and in real life.

Kerry Ingram, who plays Princess Shireen, said she often had to go to the studio earlier than her co-stars would be dressed. The head of Costume of the Kingdom of Barry Gower's costume department said Shireen's skin was disguised as the skin of the elephant or the cracked riverbeds. Actors of agar usually take up to 4 hours to disguise before each scene.
