House Caelthorn, bearing the sigil of a crescent moon and a hawk in colors of black, green, and purple, is a stoic and honorable faction fiercely loyal to the child monarch of Thelidor. Torn between unwavering allegiance to the crown and the urgent defense of the southeastern border against the Hesan Empire, they view House Durnmere as lacking austerity and House Halebrandt as dangerously power hungry.
Political Position: Isolationist and defensive. Arthur Caelthorn believes Thelidor must first secure its borders before meddling in court politics. His withdrawal from the capital is both a strategic retreat and a silent protest.
Lord Arthur Caelthorn - head of the ancient and noble House Caelthorn, a family with a long history of loyalty to the crown of Thelidor. He has spent his life serving the kingdom with unwavering dedication, but recent threats from the Hesan Empire on the southeastern border have deeply concerned him. Arthur is stoic and reserved, often keeping his worries to himself, especially about the dangerous infighting among the three noble houses of Thelidor, which he believes is weakening the kingdom.
Lady Milfrey Caelthorn - devoted and optimistic daughter of Lord Arthur Caelthorn, known for her friendly nature and stubborn loyalty to her father and house.
Lyle Grandview - clever and enigmatic human politician serving as chief visor and Castilian to Lord Arthur Caelthorn, known for his warm charm with nobility and cold dismissal of commoners.
Sir Robert Drayton - An old, one-eyed paladin of Caelthorn, poetic and loyal, who once served King Bertram and now advises Lady Milfrey while guarding court secrets.
Holden Caldwelle - Holden Caldwelle serves as chief regency administrator and barrister for Lord Arthur Caelthorn, whose lands border the troubled region of Alendria. With Lord Arthur increasingly absent due to rising Hesan threats, Holden has become the voice of Caelthorn in Delia. Known for his meticulous nature, Holden insists every agreement be formalized as a signed treaty. Though often overwhelmed by the contemptuous Halebrandt and the rhetorical slipperiness of Durnmere, Holden remains a steadfast guardian of legal order.
