The letter K represents King Arthur and the Knights of the Round Table.

King Arthur is a legendary British leader who, according to medieval histories and romances, led the defence of Britain against Saxon invaders in the late 5th and early 6th centuries AD. The details of Arthur's story are mainly composed of folklore and literary invention, and his historical existence is debated and disputed by modern historians.

The Round Table is King Arthur's famed table in the Arthurian legend, around which he and his Knights congregate. As its name suggests, it has no head, implying that everyone who sits there has equal status. The table was first described in 1155 by Wace, who relied on previous depictions of Arthur's fabulous retinue. The symbolism of the Round Table developed over time; by the close of the 12th century it had come to represent the chivalric order associated with Arthur's court, the Knights of the Round Table.
