Isabel was a companion of Ember, who always followed him, although they constantly clashed, they needed each other to hunt, and when his companion hooked a pack before his eyes, Isabel followed in his footsteps and was eventually accepted since his companion had been too, he had formed a strong bond with Ember and was unwilling to leave him.
Isabel is a wolf of few words, usually being stuck with an expressionless face. He is cold and doesn't seem to care about the others in his pack, always working alone through the shadows of the forest to accomplish his goals. When confronted, Isabel will use more words than actions, but will not hesitate to put another canid in his place if the situation calls for it or if he wakes up on a bad day.
Many wolves in his pack say he is empty inside and should not even be considered a pack wolf since Isabel is rarely seen by the others, always being on patrol at the borders. Isabel has always handled rumors very well, but it's not like he's always in contact with them, for the reason already listed.
The wolf is more of an observer than anything else, and it's no wonder he has become known as "The Sentinel" by the canids. Even the higher-ranking ones fear the canid, for they say that it is always prowling in the darkness and is hardly noticed, so it wouldn't be hard for it to get wind of rumors, conspiracies, or to eliminate someone at the alpha's command. However, the canid has already shown himself to have his own opinion about his alpha's administration, and even if he is loyal to Teemana, his actions can be somewhat dubious.
