Fae names are exchanged frequently. The focus of the power is determined by the individual who bear it. Knowing an individuals title is very important as well as there specific modus-operandi.
A fae can live eternally, constantly reviving and dying in a continuous story. They are interwoven with stories so much that simply attaining a title can give them a great deal of power. The average fae soldier is tall, skinny and adept with magic. A single contingent proved a great deal of trouble. Also the fae have an ability to "claim" location in Creation, allowing them better access to the fae plane of existence allowing them to continually transport fae to Creation.
Fae are susceptible to their stories. An individual who uses witty banter, can cause a fae to give up vital information even if the fae knows what the individual is doing, thus individuals who know how to story-craft such as Amadeus, the Bard, or Catherine, can often times confront Fae who are considerably more powerful than them, if they know the story and role.
Fae, while extremely powerful in their own plane of existence, allowing them to draw on a far greater well of power, prove extremely weak by comparison when they enter Creation.
