It was widely believed that every genie had the innate ability to cause misfortune to befall another simply by looking at them in a distasteful manner. The effects of this curse ranged from a slight case of bad luck to full-blown tragedy.
Being magical creatures, genies did not need to be physically present before an individual to invoke this power. They could curse someone with the evil eye simply by spying on them from afar.
The evil eye was not necessarily a magical ability, but rather a simple part of life in a land full of genies.
The simplest way to get cursed with the evil eye was to fail to exhibit modesty when presented with a compliment or praise. Performing amazing feats and then boasting about them usually made genies jealous.
