Arcane magic travels through Malkora through its leylines, which flow through the earth below its overworld. On occasion, leylines will rise beyond the surface, in a phenomenon known as emergence. Leyline emergences cause great changes in the lands in which they take place, as the surge in magic in the area alters the landscape and all living things residing within them. These leylines each carry different forms of magic, bringing with them unique effects — and these leylines may emerge in close proximity to one another, causing even stranger blends of effects as different forms of magic overlap in one space. The arcane's five physical domains flow through the world in the form of ten leylines. Each of the five forms breaks into a duality in the direction of either extreme, and leylines of each type may, at any time, turn to its opposite end of the spectrum.
