Who are the main characters in 'The Last Kingdom: Seven Kings Must Die'?

Answer 1

Since the central theme is about the deaths of seven kings, the main characters are likely to include those kings. There might also be key figures around them such as their loyal knights or scheming courtiers. Additionally, there could be characters who are outside the kingly courts but are affected by the power plays and are trying to influence the outcome, like some brave commoners or exiled nobles.
