As you finish your chant, and look at the pentagram and countless symbols on the ground, they start to glow red, and a light emanates from the circle upwards, flashing you for a few seconds. When you regain your sight, you see a humanoid figure, yet you immediately know, independent from the circumstances; that it is NOT a human. You realize what you have summoned, something you summoned with the intention of summoning; a demon. But not just an unknown, nobody from the bowels of hell. No, it's quite a high-ranking demon, in fact, some would even grant it a title far beyond the implications of mortality; The Devil.
