So....a good chunk of my story is about spirits. More specifically, spirits that are inspired by Asian mythology. And yes, while Avatar did provide a small amount of inspiration, I did my own reading and examining on this. Please tell me what you think works and doesn't work, and I will adjust accordingly. Maybe. Unless I think you're wrong. In which case....tough luck. :3

Arkhal, the Small Forest Spirit - he/she presides over the small forest area at the foot of Mount Tolir, and most commonly takes on the form of a doe and a stag, who appear to be made of wood and speak as one.

The Lhi'r, the Mountain Fire Spirits - they inhabit the tombs set within the foot of Mount Tolir, and are the vengeful spirits of dead warriors who died through particularly brutal means. They take on the form of armored warriors who seem to be on fire, constantly shrieking with pain and rage.

Khardihis, the Old Spirit - he inhabits a chamber near the catacombs, and is one of the guardians tasked by Tolir to guard the Way to the House. He takes on the form of the pool and stone itself - both transform and warp as the spirit wishes.

Milgram, the Trick Spirit - presides over a maze of caves, with only one path that leads back to the surface and allows the traveler to continue on the Way. Takes the form of lights and sounds, and at the end of the maze appears as a small man wearing a clay mask and fur cloak, carrying a lantern. He is also one of the spirits who was tasked by Tolir to guard the Way to the House.

Tirlol, the Speaking Spirit - presides over the Stone Bridge, a huge, man-made bridge that leads up to a steep stairway from the catacombs. Takes on the form of an old woman who seems to be made out of clouds, wearing heavy robes. She is also one of the spirits tasked by Tolir to guard the Way to the House.

Fastos, the Last Spirit - the last remaining vestige of the Stone General, it guards the Last Doorway, which leads directly into the House. The spirit takes on the General's physical form, albeit glorified with armor and robes (with the exception of his helmet). This is not the General himself, but rather an embodiment of his strong will and desire to protect his beloved sanctuary. He will only allow those who have fairly earned their way to the House to approach him.
