Fey are typically territorial. This is because land means resources – food, shelter, space. Greater Fey will hold large swaths of land – the most successful owning territories the size of countries. Within those, Fey and lesser Fey will make their own miniature dominions. Fey will fight to gain or protect their territory and their belongings. Violence over small robberies is just as common as wars themselves.
War is common, but generally short-lived. Most Fey don’t have the desire nor patience to hold a long term war, and Greater Fey may not have enough power and control to keep the Fey and lesser Fey fighting. The average war lasts about six months, but they are brutal, bloody months. Lesser Fey and average Fey will unite under greater Fey in the hopes of receiving greater prizes than they could have ever gathered themselves. However, if it becomes obvious that the other side is winning or more advantageous, Fey will not think twice about betrayal.
Warfare is brutal, bloody, and disorganized. Strategies are hard to execute with impulsive Fey. As Fey despise iron and silver, they fight primarily with whatever magical abilities they have. However, bronze, wood, and stone weapons are used as well. Guns, cannons, and advanced weaponry have not been introduced to Fey. Therefore, they are limited by the weapons they were familiar with before the Feylands. Fey enjoy mixing magic and weaponry, whether that be using a magically fortified bow to better aim lightning, or encouraging a charmed sword to burn the flesh off of enemies. Charms are heavily used in Fey warfare.
Greater Fey can cause extreme damage and casualties. Those who have magical gifts and can manipulate parts nature (often called terraforming) can create tornados, cause avalanches, and encourage rivers to flood or divert themselves. Some Greater Fey maintain dangerous reputations due to their savage warfare.
