Siku


A young girl of the Khinu tribe, the indigenous people who lived among the perpetual snow at the border of Wikhatt, Brittia, and Kaplan.
Wikhatt had oppressed the Khinu people many times before, but during an unprecedented large-scale attack, her village was burned down and most of the villagers were slaughtered. Siku managed to flee toward the Kaplan border with a few surviving children, but was nearly caught by Wikhatt pursuers until she was rescued by Gilbert Winterguard.
Afterwards, Siku became Gilbert's aide, waiting for a chance to take revenge on Wikhatt... though somehow she also ended up playing a big role in waiting for a chance to take revenge on Wikhatt... though somehow she also ended up playing a big role in exaggerating Gilbert's accomplishments.
