The royal symbol of King Henri is a prancing bull
King Henri was the king of Gallica. He maintains a court in the south of the country. He is said to be old and not a strong leader, so there are many warlords in his country such as Depernieux who can do what they want. The only cities he controls are his court and the harbour-city of La Rivage. He does, however, sometimes send messengers to other kings and rulers.
This is mentioned in The Icebound Land and Oakleaf Bearers. He apparently lost his crown to King Philippe nine years prior to The Missing Prince in an uprising.
