13 Kingdoms and all these different noble houses

Have thoughts on a noble house that you think should exist in this setting?  Well comment some thoughts here.

House DeWinter - A strong merchant house with many shady dealings. Will do anything to make a profit. They attempt to put on an honorable face, but any wily House would know the truth. They have a "code of conduct " regarding how they handle dealings, but in the fine print, they will always come out ahead. Think Ferengi from Star Trek, House Lannister, from Game of Thrones, and maybe a little Machiavelli family thrown in as well.

House Y'avrul, The noble intelligence gatherers, rumors float around of them being assassins trained from a young age to ensure safety of the Kingdom's interests in secret. Naturally those caught "slandering" the good name of the family meet a swift death soon after, silently spreading the rumors even more. Think of Killua's family from Hunter x Hunter, or the Hyabusa ninja clan from Ninja Gaiden. They usually move in pairs and almost never reveal their actual identities. The pairs are formed as young adults and remain for 10 years at least, when they are finally cleared for solo operations assuming they performed well enough.

So what kind of planets would these houses be on or are they not houses holding a system / celestial body / space station?

Hello everyone, i just joined the game.I had a question, if we can create our own houses, could i create a Cyborg house? It would be called house Mechawald and all the members would get cybernetic implants at a very young age. The implants would depend on the job the house member is to perform. Strenght enhancement for soldier, medical tools for doctors ect... The members of the house would consider themselves to be the "ultimate humans". Their society would be very orderly and advanced.

House DeWinter, a merchant House

"Dewinter is coming.  Matter of fact, they are here with the next hardware."
