What is the significance of the tattoos on the High Table members in John Wick's world?

In the John Wick universe, the High Table is a governing body that manages all underworld activities. Its members are known for their unique tattoos, which represent their status and affiliations in the criminal world. The tattoos are highly symbolic and serve as a mark of honor, loyalty, and power.

The tattoos are designed in a way that only those who are part of the criminal underworld can identify their meanings. For example, a tattoo of a crown on the back of the neck indicates that the bearer is a member of the High Table, while a seven-point star on the hand represents the Continental Hotel.

The tattoos also play a significant role in the movie's plot. When a member of the High Table commits a crime or breaks the rules, their tattoo is marked with a black X, indicating that they have been excommunicated and are no longer protected by the organization's rules. This happened to John Wick, who was excommunicated from the High Table after killing a member on the grounds of the Continental Hotel.
