Sweet Whisper
From Mizahar Lore
Sweet Whisper is an expression often used by wizards to describe the overwhelming temptation to cast more and more magic, especially when already under magical stress and exertion. It chiefly refers to personal magic, though it can also apply in a broader sense to all magic as the enticing prospect of discovering more, knowing more, crafting more. It is named after the fact that some wizards actually start hearing voices in their head when they approach their magical limits. Usually, this is just a symptom of magic delusion, a common mental disorder in wizards that gives them a feeling of omnipotence; in a few cases, however, this turned out to be the work of powerful extraplanar creatures contacting the wizard.
