Warden

Warden is exactly what she's named. A warden of the forest. Her forest. She guards her territory and anyone or anything seeking refugee inside. She's a guardian and accepts any creature that's injured, sick, or even the elderly to pass on peacefully. She is a shy creature but very curious. Often observing others from a distance but almost never gets close enough to be spotted. However, she is very territorial and will not tolerate other creatures hunting in her territory. Her home is a place to either heal and move on or spend one's final days in peace. Creatures know about Warden and named her Warden of the Woods, or her foes the Wooded Devil. It's rare for any creature to ever spot her, but the few who do say she gives a calming presence and those who trespass and cause problems never live to tell the tale.

Warden is a Helhound (my personal version). It's rare but when enraged she will grow in size and power to defend what's hers. Her archdemon form is rarely seen, for unlike most hell hounds, she's very calm and level headed. She made her home in the mortal realm to escape the drama of her family's pack.
