Khun Maria Zahard

Koon calls her his older sister, but also says they have different mothers and that they "were more distant than any other". He describes the sister whose place she took as his biological sister which implies that maybe Maria is not his biological sister. Koon describes Maria as kind, polite and as a woman who knows how to care for other. Koon helped put her in a position "seated next to the king" that his biological sister once occupied, but sense then his heart has felt empty. Possibly the reason he is climbing the tower is to recover what he lost at that time.
