Write a character description for a fantasy rpg: Isaac Sisur is a Troll Male that lives in Grazelas.
assistant
Isaac is a massive troll who stands nearly seven feet tall. His heavy brows and fierce expression give him a look of grim determination, yet there is no mistaking the gentleness in his voice when he speaks. While he doesn't seem particularly old, he bears more than a passing resemblance to the ancient troll kings depicted in some of the elder tales. Isaac is dressed in forest greens and browns, his arms bare save for metal bracers. A deep scar runs along his right shoulder, evidence of past battles.
