Mundanes. Mundane humans have no powers or abilities. They were born to human parents and, unless something dramatic happens in their life, they do not know that the Sidewise exists.

Psychics. Psychics are humans or near-humans who have, through birth or accident, acquired the ability to do exceptional things. Some of these abilities are small; lesser psychics might have minor abilities like the power to create a small flame, to communicate silently, to tell if people are speaking the truth, or to levitate small objects. Other abilities might be much more dramatic. Greater psychics might have a suite of powers related to emotion or thought, or might be able to fly or teleport. The thing they all have in common is that their powers are innate, and require no external elements. Sometimes, over time, these powers grow or develop.

Magicians. Magicians (also sometimes called witches, wizards, mages, or a dozen other names) are humans or near-humans who have acquired magical abilities through learning. Most creatures are born with the ability to do prop-based magic, but it takes a specific kind of mind and focus to learn how to use it. Those who have studied and learned how to hone their skill are able to use herbs and other ingredients along with incantations to create magic. Often, they have a book to keep track of what spells have worked for them and what haven't. Those who have been practicing for longer tend to be more skilled.

Magical Items. Some humans or near-humans may find magical objects or familiars that gift them with special abilities. These could include weapons, wands, armor or clothing items that attune themselves to their owners to give them minor to major magical power.

Curses. It's possible that if a person crosses the wrong creature, they may end up cursed. Naturally, curses will result in problematic effects for their victims. Somehow, though, they also give magical abilities or other supernatural elements that can be used to a person's advantage.

High Technology. While it's not magic, of course there may be people in this world who have far surpassed the standard technology of the era to create fantastic machines, or to augment their bodies, or a hundred different things.

The Fae. The fae have been part of human culture for a very long time, and the name covers a very wide range of creatures. While the High fae might be gold-haired and beautiful, there are many other types of fae that are quite different. There are myths about wild creatures that hunt human beings; there are leprechauns or brownies; there are trolls and goblins and everything else. This is an incredibly wide range of creatures.

The Undead. The undead are often (but not always) creatures that were once human, but who after their death -- or sometimes not -- end up in a place between living and death. This category may include Vampires (of which there are many kinds), zombies, mummies, or many others.

Spirits. While some spirits might be wrapped up in the category of the undead, might take the form of ghosts or the lost souls of dead humans or other creatures, that is not all spirits. All that spirit means is creature not bound by its physical body. Some of them may be able to take on physical form, and other may not. There are many beings throughout history that fall into the realm of "spirit".

Demons. This is not demons or devils, necessarily, as they appear throughout western religion, though some of those may be closely related. Demons are creatures from another dimension or reality; they're beings that step into our world and, when they do, they have exceptional powers that follow them. Many of them are monstrous in appearance, but this can vary from one to the next.

Shifters. Werewolves are the classic type of shifter, but there are many others -- from people who can turn into animals to people who can take on the form of smoke and many others. Shifters are beings with two or more shapes,

Other monsters. Naturally, there are all kinds of other monsters that exist out there. These are here only as a guide; if you have an idea for something different, please, be creative!
