Enhancing the caster's passive psychic talent, this metaspell allows a mage to continue to receive incoming thoughts on the gweth network even after their self-cast Thoughtcast spell expires (always, or indefinitely until death or whatever). Thoughtcast needs to be re-cast before outgoing thoughts can be sent again though. This could make Thoughtcast a more viable alternative to gweths without completely removing the need to still occasionally cast the base spell. Maybe it's called Clairaudience or something.
