From the introduction:
Modern Magika is a supplemental book for the Ops and Tactics roleplaying game, focused around elements of fantasy, magic, and the supernatural. It makes elves, dwarves and other fantastic races available to create characters from, and introduces several new systems of magic with highly customizable effects, along with artifacts and new equipment associated with them. Standard magecraft revolves around the user’s intelligence, and draws its power from written words and formulas of power. Whether a spell is scrawled with crayon or scribed on fine parchment with high-quality mystical inks, the pen is mighty. Psionics revolve around the user’s wisdom, and draws its power directly from the mind and body of those practicing it. Whether that power is focused within or without, psions are flexible and able to shift their focus on the fly. Incantations revolve around the user’s charisma, and draw their power from spoken words and languages of power. Whether summoning shadowy beasts or inflicting hexes, words can very much hurt you. With the inclusion of adventuring equipment, Modern Magika can be used to run modern fantasy games as readily as it can handle a more fantastical game, or anything in-between.
