The three snakes mentioned at the beginning of this game are important symbols. They represent the three political factions in the capital, the King's Faction, the Queen's Faction, and the Princess's Faction.
The King's Faction is a civilian rule that advocates nationalism; the Queen's Faction is a rule that advocates multi-ethnic equality; and the Princess's Faction is a militaristic dictatorship.
The symbol of the King's Faction is a book (knowledge), the Queen's Faction is a skull (magic), and the Princess's Faction is a sword (force). I don't know if the initial choice of profession has any impact on the development of the plot. If so, it would be too complicated.
At present, the main factions of the characters are distributed as follows: King's Faction (King, Ludwig, Pretorius); Queen's Faction (Queen, Alaina); Princess's Faction (Cassandra, Guran, Aker); Unknown Faction (Arcadia, Conrad, Callahan). Arcadia obviously doesn't like the Princess's Faction, and it feels like she may be the Queen's Faction. As for external forces, the North (Aurora) may lean towards the Queen's Faction; the South (Isis) may lean towards the Princess's Faction; the West (Priscilla) may lean towards the King's Faction.
There are conflicts among the three factions, but the Queen's faction is more friendly to the King's faction and more hostile to the Princess's faction.
