Information on them:
Merc Kats are a male only race of mercenaries who live in a kingdom on an island serving their King. They are completely alone on this island except for any mates and children they have. Wolf like in appearance, they are very business minded and loyal to their king. They each have a job and follow it completely. They are to check in with their king frequently, and do their jobs discreetly. They are Mercenaries by nature and regular ones(not working for the king) can be hired for any job by other kats.
Their wings are sharp and made of metal, they are meant as weapons and shields more than to be used to fly with. The Mercs are strong enough that their strength mixed with their magic allows them to use their wings for flying, but they don't typically use them for non battle purposes.
Long ago the Merc God worked up a surprise with the Kryenae and gave the King a small robot as a reward for all of his hard work in keeping track of his men. But not long after that, the God and King found they had to use the robot for a secondary use; more than just keeping track of missions. Some ebil kats were trying to steal the Mercs eye pieces and use them for themselves. From that day on the King decreed that all Merc's had to have their eyepieces attached to their heads at birth. So, he enlisted the help of the kryenae who worked with the Mercs to update their tech, to modify it to be a part of them. They also made it so the King could technically control them if he so wanted to. Like an army.
You see, these eye pieces are very special. Alone, by themselves, they are nothing but a material accessory. But, when worn, the user's magic activates it making a resource for the Mercs. Whatever or whoever they look at the eyepiece scans and tells them what they are looking at. A reading displays on the eyepiece itself showing them what they are looking at, or the race of someone living. Anything known about that race or that thing shows on the 'screen' next. They also link up to each other so any other Merc can see what each one is looking at. The King's robot can take all of the information and store it.
Merc Kats are strong and powerful, both physically and magically, but they are to act responsibly with it(no god modding). They care more about their own agenda than about others, and their main reasoning for breeding is for bringing more Mercs to the kingdom. They are completely business minded and always neutral.
