But the Prince, who was quite immune to the many enchantments of his brethren, did not forget and he asked the Knight what quest she was so set upon to brazenly break into his Tower.  

“What know you of Zvestren?” she asked with weary candor.

“You mean Zvestren Fel Duskwing?”...he muttered, “one of my many brothers that no one cared to remember”.

And with that, the Knight leapt with joy, “Zvestren Fel Duskwing! this name spoken true will save the day, I will banish him once and for all!” 

And at that she thanked the bewildered Towermage and hurried back to her small kingdom, confident that the angry spirit would finally be appeased.

Hello, hope your all doing well. I've been battling allergies all month and trying not to fall asleep at my desk from all the antihistamine.

Anyways, Our bad guy mage has a name now! I'm not surprised the Exiled Prince knew him, he is pretty much related to every fauni ever. Too bad the Moon Knight couldn't really stick around, people in exile do not generally get a lot of visitors.
