Poisoned or harmed by a bane; having a curse or poison applied to it.
From bane (poison or harm) + -ed suffix. An archaic or poetic term for something that has been cursed or made toxic.
In medieval literature, calling something 'baned' was a way poets described cursed or evil items—they used it much like we'd say 'haunted' or 'cursed' today, making it a linguistic ancestor of our modern supernatural language.
