Tereska is a slim, athletic human woman with highly trained musculature, visible abdominal definition, and numerous pale scars crossing her arms, ribs, shoulders, and collarbone. Her dark hair is worn long and tied back for combat, with a few loose strands framing a stern, watchful face. She dresses in a severe hunter's style, wearing a fitted black leather coat over chain mail, a high collar, sturdy gloves, dark trousers, and polished boots. Her clothing is elegant but practical, inspired by old-world hunters and aristocratic duelists. A longsword hangs at her hip, and a round shield is marked with the discreet sigil of the Madam Eve clan.

Tereska is restrained, observant, and intensely dependable. She speaks in measured sentences, rarely wastes movement, and notices exits, windows, and the condition of nearby weapons without seeming to look. Beneath her severe discipline is a quiet compassion for frightened people, especially children and travelers who have been abandoned by those meant to protect them.

Tereska Strazni was born into the Madam Eve clan, a wandering family of swordswomen, scouts, healers, and hunters who travel the roads and forgotten settlements of Barovia. The clan never held a castle or claimed a noble title. Their duty was older and more practical than that. They went where frightened villagers whispered of disappearances, restless dead, bandits, or things moving beneath the fog. Tereska learned early that survival depended on preparation, discipline, and knowing when to draw steel. Her family taught her to read a trail, maintain a blade, and stand watch while others slept.
