How long can you be knight?

In many fantasy settings, a knight can hold the title for life, as it is often bestowed as a mark of honor and loyalty. However, in historical contexts, knighthood could be lost due to disgrace, failure in duty, or the death of the monarch who granted the title. In some cases, knighthood might also be hereditary, passing down through generations. Ultimately, the duration of knighthood can vary significantly based on the specific traditions and rules of the society in question.
