Morvidus (Welsh: Morydd map Daned) was a legendary king of the Britons from 341 to 336 BCE, as recounted by Geoffrey of Monmouth.
After the battle, he had every captive soldier brought before him and personally killed each one, feeding his lust for blood.
For this reason, he is associated with the symbol of a ragged staff, which appears in the crest of the Earl of Warwick who are believed to be descended from Morvidus.
[3] Later in his reign, a dragon or monster appeared from the Irish Sea and began devouring the inhabitants of the western shores.
Morvidus had five sons: Gorbonianus, Archgallo, Elidurus, Ingenius, and Peredurus, all of which became kings of the Britons.
