Magic
There are many types of magic in the world, only a few are very well
documented.
Sorcery
Basically sorcery consists of drawing on a source of energy and directing
and shaping it. What this source of energy is exactly is unclear, it’s
pretty well known that it is extra dimensional however. It’s often called
simply ‘The source’ or ‘The Ocean’ some believe it’s an ocean of energy on
some other world, others believe it’s some kind of deity.
Opening a way to this energy allows it to flood through, opening the way
further, it can then be transformed into other forms of energy and directed
as the wielder wishes.
Humans are not usually capable of this type of magic.
Rituals
Rituals are a type of magic that can be performed by almost anyone. All
they require is access to the proper instructions which every society
library should have. They also require specific ingredients however, in
particular they require human blood.
It’s believed that rituals function by draining a form of energy from this
blood, which is then fed through the ritual to spirits who carry out the
request. Exactly what these spirits are or where they come from is unclear.
