Spruce Troll
Spruce Trolls have long been both the enemy and friend of the Walmerian people. These terrifying, blue skinned humanoid monsters, with fearsome tusks and more terrifying fists, inhabit the forests of Walmer where they fight the other giants. Though they seem to have humanoid traits, they're as dumb as a rock and easily satisfied. They are forced to eat meat and can eat nothing else: giving them a goat a day will keep them happy, and when kept up for a certain amount of time, it turns them fiercely loyal. They use the massive trees of the forests as their clubs, and have never been seen retreating from a fight. When the fighting gets tough, they enter an enraged trance and will gladly fight to the death. The greatest enemy to a troll-keeper, however is famine. When Trolls are not supplied with a decent amount of meat, they will gladly eat a human or two.

Walmerian Mountain Drake:
While for most, summer nights are marked by the sound of cicadas and crickets, the nights of the Walmerian mountains are marked by the impressive shrieks of the Walmerian Mountain Drake. These horned, reptilian beasts, roaming the peaks of the Walmerian Mountains, often duke it out over territory, food and mates. Their impressive horns and scale armor have proven them to be incredible melee fighters, but every Walmerian child knows that their spurts of flames also make them formidable as an opponent. They have been used as beasts of burden for generations, easily pulling heavy carts up steep mountain slopes and drawing ploughs through the stoniest fields. They are solitary by nature, and it takes quite an effort to socialize them towards both others of their kind and people while they are young.

Glacial Spirit
Long it was believed that the Glaciers of our nations harbored the spirits of our dead. Uncanny sounds, glimpses of people and bone chilling coldness were common experiences for those traveling along these massive walls of ice. It took some royal expeditions to finally dispel these myths. Glacial Spirits turned out to be small, ghostly monsters, inhabiting cracks in the ice. More research gave us a method of carving runes in rocks that appeal to these creatures, who started inhabiting them. Now, it is not uncommon to see a runestone floating around, surrounded by whatever ethereal shape the spirit decides to take on. They posses decent psychic powers, yet if their runestone is damaged, they'll quickly vanish into thin air, never to be seen again.
