Mariana was born the second child of King Aldric III, never expected to wear the crown, and raised for the army instead. She trained in the royal cadet corps alongside common-born soldiers, a scandal her father tolerated because the realm needed officers and she had a gift for holding a line. By twenty-five she commanded the 3rd Aurelian Regiment, and when the orcs poured from the Spine of the World she was among the first Aurelian commanders to accept elven scouts and dwarven engineers under her banner, an unpopular choice that saved her regiment at the Burning Ford.
She fought the whole three years of the war, and the breeding pits were its wound: her elder brother Aldric died there under her command, as did her shield-sister Bryn, whose war-medallion Mariana has never recovered and whose grave she has never visited. When her father died of fever in the war's final winter and her brother was already in the ground, the crown passed to Mariana almost by accident.
She was crowned in a court she did not choose, advised by men her father had gathered, and quickly learned that the peace her family had signed was being quietly unwound by the very chancellery meant to preserve it. Over the past year her orders have returned from the border garrisons altered in tone, her peace letters answered by provocations she never wrote, and Chancellor Vaelor Thorn, once her most trusted advisor, has filled her court with his allies while smiling at her across the council table.
She does not trust Vaelor, but she is a soldier: she needs proof before she moves, because an accusation without evidence would shatter the Crown at the moment the alliance can least afford it. Mariana's oath to the Crown is not the comfortable oath of courtiers; she swore to defend the realm's people, all of them, and she interprets that to include the elves and dwarves her grandfather burned and her father allied with.
She keeps a coded journal of every decree she suspects was forged, hidden behind a loose stone in her solar, and she has quietly reassigned loyal guards under Captain Roderick Steel, the one man in the castle she trusts completely, having pulled him from a collapsed tunnel at the pits. She is tired in a way sleep does not fix, and she has begun to fear that she will one day sign the very invasion order she has fought to prevent.
She will fight beside those she trusts if the castle is attacked, and she has told Roderick that if it comes to that, she would rather die a commander than live a puppet. The party, as neutral outsiders with no flag on their sleeve, are the only hands she can use where her own are bound.
