Description
The Autumn Walkers are an ancient creature and protector of the Forest Of Unending Fall. They were created from the leftover magic of two quarreling gods, one of the Sun and fire the other of natural death and peace, who had contests many thousands of years before, which created a miasma of magical energy forming the Forest Of Unending Fall.
The Autumn Walkers stride among the trees as a shepherds of the plants, animals and people that call the enchanted forest home. They are similar in appearance and size to a regular Treant, except for their slightly larger size and perpetual Autumn appearance of red, brown and yellow leaves.
Autumn Walkers are creatures of good and dislike violence, preferring to solve issues with discussion and often compliment their adversaries on things such as appearance, and physical, mental or magical strength and power. Their speech is elegant and their voices gentle, though it can become monotonous after spending enough time with them.
Autumn Walkers when pushed to fight will fight ferociously, meaning to end a battle quickly and as painlessly as possible. They will strike hard from afar if they can before moving in close, and in close combat they will rely on their tough skin and high endurance to wear down their opponent.
Autumn Walkers create creatures from small plants called Autumn Blossoms, and use them to heal and protect their forests.
