Mage: The Ascension
"A modern-day game of secret magic¸ where magicians from nine rebellious traditions struggle against the Technocracy -- a group of magicians who are trying to control all magic within reality¸ enforcing the limits of mundane science for everyone except themselves. It uses a variant of the ""Storyteller"" system originally used in Vampire: The Masquerade. It has a magic system with effects in several broad spheres¸ where due to the Technocracy¸ magic is made more dangerous if the effects visibly break physical laws -- but are allowed if there is a plausible mundane explanation. - A description from https://darkshire.net/jhkim/rpg/encyclopedia/ with kind permission of John H.
