I feel no guilt for using Butchers work in my game
It's good work and he's a good writer.
My Fey World is actually another world, geographically identical to our world, but inhabited by entirely different creatures and plantlife and so forth.
The Sidhle (Elves - although all non-human races, giants, elves, etc. live in this other world) have the largest and most advanced kingdom (their capital is at Samarkand) in this Other World and they have a highly advanced magical "technology." (It doesn't work like tech but can often have effects like a technology, so I use that word for convenience.)
The technology causes mutations in living things however, if used often enough, and can sometimes result in mutated elves and player characters (Korruhn) and also in monsters (Korreupt). So the Sidhle are looking for new forms of magic and since they can cross into our world they have become interested in human religion and thaumaturgy (wonder-working, or what is more commonly known in most games as clerical magic, though it works differently than most clerical magic, because God controls how it works not the cleric) which they see as a possible replacement to their elturgy (their arcane magic). (There is no Arcane magic in our world, and no Divine magic in their world.) The Court at Samarkand also has access to secret magical technologies and devices and artifacts which only they know about (such as telescopic "chairs" which compress distance, or allow them to see short distances through time, or even into our world, to name one such artifact) and so the priest king uses these devices when trying to make decisions on what to do. Though some suspect these secret technologies exist, and who controls them.
Because of all of these things there is a great deal of religious, political, social, and cultural intrigue, as well as intrigue among various city-states and nation states, and even among races. The Eladarin are extremely opposed to Sidhlen experiments with human religion and thaumaturgy. Some races are neutral on the matter, others supportive. The leader of the Sidhle also wants to promote good relations between humans and his kind and to promote in his world what might be called democratic virtues to us, and to slowly transform his kingdom into a Republic. Other races are less than enthusiastic about humans and/or about political reform.
There are no courts, per se, rather there are a series of groups and organizations and powers and individuals all with their own thoughts and agendas concerning arcane magic, how monsters are created, how to relate to humans, how to relate to God, how to relate to other races, thaumaturgy, politics, culture, and so forth. It all mixes together.
The humans consider the Sidhle and their leader the likely Kingdom of "Prester John."
Although some humans consider the Sidhle and the races of the other world to be monsters, or even demons. Agents of evil, corruption, or outright satanic.
