Therru

Therru is a young girl who was abused by her parents. She was taken in by Tenar.

Therru has brown hair with two long strands in the front where it is tied with red ribbons. The rest of her hair remains short in the back. She has brown eyes and a large burn scar on the left side of her face due to her parents burning her. Her attire is a plain, dark pink jumper with a lighter, long-sleeved pink shirt under it as well as a white apron in the front.

Therru is quiet and never talks to strangers. She's independent and speaks her mind. Despite this, she's very caring towards her acquaintances and animals.

When Cob tries to strangle Therru to death and believes to have succeeded, she is revealed to be immortal. Cob starts hobbling towards her rasping for "Eternal life", but she transforms into a dragon and blows a ball of flame onto him, causing him to catch on fire to eventually fall to his death due to a collapsing stone.
