Halesola rules Atland, a nation clinging to survival beneath an Orbital Spire Tree in a frozen world. He is the father of Liliha and Yaona, possessing blonde hair with blue streaks and olive eyes. His kingdom faces constant threats from Valghia, a rival nation determined to seize Atland's scarce water.

When Valghia captures his daughter Liliha, Halesola refuses Commander Olinoga's plea for a rescue mission. He prioritizes Atland's security over individual lives, stating he will not risk his nation for one girl. This choice underscores his leadership approach, focused solely on pragmatic survival amid relentless conflict and dwindling resources.

Halesola views Kaina, a youth arriving from the Canopy membrane above the Snow Sea who becomes involved with Liliha, with deep suspicion. Doubting Kaina's claimed origins, he considers the youth a potential Valghian spy. As a precaution, Halesola orders Kaina placed under guard upon arrival in Atland.

His relationship with his children intertwines with political duty. While refusing to risk rescuing Liliha, he permits his son Yaona to participate in missions, showing a willingness to involve family in state affairs despite dangers. Halesola's leadership decisions, including the initial refusal to save his daughter, stem from his perceived duty to safeguard Atland's stability above personal family ties.
