Election d'Arthur Pendragon

At Carlion the Supreme Collegium is summoned to select the new High King, an office which has been empty for many years. Many of the kings do not attend, but those present are sufficient to elect their leader: King Arthur of Logres.

Thus King Arthur is elected to be Imperator and Caesar of Britannia, and Wledig (or Chief Warlord) over the British Tribes. He takes the arms of the High King at this time: a blue shield with three gold crowns.
  The festivities are tremendous, and no one is disappointed. Many of the sub­kings come, including especially King Lak of Estregales and King Alain of Es­cavalon.
  Amid the celebration Arthur learns that six northern lords have arrived at the city. He sends them presents and bids them welcome, but King Lot and his al­lies insult the messengers and the boy king instead, "and said they had no joy to receive gifts from a beardless boy that was come of low blood."
  Frightened by the huge army, Arthur orders the city to be closed and prepared for a siege, The rebels sack the outer vil­lages After a couple of days Arthur real­izes that no battle can be won by hiding behind walls, and so he orders his army to assemble and to fight.
