Writing Mathias: ISFJ in Heart of the Worlds

A young man with shoulder-length dark wavy hair, sun-kissed skin, and striking green eyes stares ahead with a serious expression. He wears a medieval-style leather jerkin over a linen shirt, with a castle spire and autumn trees blurred in the background.

Mathias is the quiet strength of Heart of the Worlds—a seventeen-year-old Pegasus rider shaped by loyalty, guilt, and scars of the past. As an ISFJ, he embodies the Protector archetype, balancing steady devotion with the struggle to trust love and forgive himself. His story is one of duty, exile, and the quiet courage of showing up even when hope feels fragile.
