If I were in your position, I would swiftly reach out to Lord Yeesch and contemplate the option of exiling or eliminating the imposter spirits. Some of these spirits take the form of djinn, who are particularly skilled at deception, manipulating your perceptions to make you believe you are something you’re not. In certain instances, they possess significant power. Lord Yeesch has the capability to defeat imposter/djinnic beings, a challenge that is often too formidable for most to undertake.
