▲ Power Obtainment Ideas ~
△ You were standing beneath a gargoyle during a storm when lightning struck, traveled through the gargoyle, and then into you. This awakened the power trapped inside the stone and transferred it to you.
△ You were cursed to become a gargoyle or a gargoyle (you) was blessed to come alive.
△ You come from a world of stone where other gargoyle-like creatures live, and were accidentally brought to your DR by a portal or you journeyed to your DR from your world yourself.
△ You died and a scientist or doctor (maybe a relative of yours) crushed a gargoyle, mixed the enchanted stone dust with water, and inserted the mixture straight into your bloodstream, which brought you back to life and gave you your powers.
△ During the 13th full moon, the blue moon, which only occurs once every two and a half years or so, a gargoyle magically came to life right before your eyes. In order to survive, you managed to kill it and earned its powers.
