These are sigils I have created and use. They act like like cogs and gears in a machine, all working together to complete a function when assembled in the proper order. There are many more blood runes which make up an English alphabet, a writing system. The concept behind making the rune and sigils themselves, was to use straight lines, as this made them easier to draw in blood. Thus, they are called Blood Rune Sigils.
