Shapeshifters: Four forms under one personality
Shape shifting is a process of life energy manipulating where individuals have a natural talent in this rare ability. However, this leads to the loss of life energy as a new form is made, the process itself is also very painful and can even be damaging. However the more you change the less pain you feel as your body gets used to process. Too much shifting at a short time can lead to the loss of too much life energy, as described in the magic OOC, and the body will quickly fall apart to death.
Tieflings: Reborn demons
There's two subtypes to Tieflings: ones originated from infernal demons and ones originated from abyssal.
Infernal Tieflings have normally red or orange colored features and spiky wings, tails or horns. They are more resistant to fire than humans are and have the ability to control fire. Abyssal Tieflings have black, blue and violet, more flat and smooth features than infernals, because there is huge pressure in the abyss. Abyssals on the other hand are resistant to the cold and can use ice magic. Both subtypes of Tieflings are weak to holy energy and light, for example looking straight at sun will momentarily blind them, since they're hellish creatures. Tieflings aren't usually physically strong. Instead they are fast and accurate.
Tieflings holds a strange mixed Life energy of demon and human, this Life energy is very chaotic and near to impossible to control. This caused magical ability to be limited in quantity, but extremely powerful in quality. Tieflings only have an affinity towards fire or ice magic types due to this chaotic energy.
Dwarves: short, strong, fearless fighters
Being a race based around physical strength and the use of tools, Dwarves have no magical ability, their life energy is small and compact as it is used in the muscles which leads to the immense strength of these short people. Instead of using their own magic, the Dwarven race have moved on to a new rare metal found in the Meningr mountain range, a metal which holds some strange magical power. The truth, however, is that this metal holds massive concentrations of nature energy, leading to its name of 'Naturite'. It is this metal with which Dwarves forge their armour and weapons with, after the familiarisation with modern weaponry sold to the mythical creatures by human traders, Dwarves also use human firearms, using ammunition formed from Naturite.
Valkyries: Winged female warriors
In old tales Valkyries are the ones who decided which men stayed alive in the battle fields: they had the ability to resurrect them. Nowadays, Valkyries might gain a similar ability. They can collect souls from the dead and raise a ghost army of warriors. However, the skill comes with conditions. First of all, they must be skilled warrior who have gained reputation among other Valkyries and maybe even among other mythical creatures. Secondly they must be at least 22 years old. Thirdly there must be no humans who could have seen them and stayed alive. Even if these three conditions fulfill they might not get the ability. It all depends if they get their god's blessing. And if humans capture them they lost their skill immediately.
Since all the Valkyries left are females, the race is near extinction. No tale tells how it's even possible to have a race without any men. Some old books however mention Valkyries being children of a god and a human.
Cerberus: Three headed hellhound
They have ability to take control over either fire, shadows or earth. Fire can't hurt them but instead being exposed to too much water will make them weaker and might affect their ability to use magic. They can't stand daylight, although they don't burn or are killed by that. It just hurts their eyes and if Cerberus is too long in bright sunlight, they may become momentarily blind. They have, however, extremely good night vision. Seeing Cerberus is extremely rare since they prefer to stay in shadows and move at nights.
Cerberus has an ability of telepathy of sorts. However they can't decide who they talk to but everyone in certain range (what you could compare loudness of regular speech) can hear them. But everyone around them are able to understand the speech so they can communicate with others without problems.
With three heads, Cerberus hold three different life energies which intertwine and fight as the creature continues to live. These three energies can only hold the affinity of one magic type and can never be improved. It is rare for Cerberus to control all three magic types of their race, most often they only control one. The affinities of the three life energies is random. If more than one life energy holds the same magic type, the magic that is used is much stronger, controlled and mastered.
Humans: Not a mythical creature
Ordinary people with ordinary jobs and ordinary daily life. Most of them doesn't believe in mythical creatures, others do but even they have never seen one (or at least haven't survived from it). Do they believe in myths or not: it's up to you. However there's also the darker side of the human kind: The H.O.N -members that hunt and sell mythical creatures or parts of them.
