Best worlds for a kingdom

Oasis Springs, one of my legacy saves, is an ancient Egyptian-style world.

This world is inhabited by a royal family that has inherited the name Landgraab for generations.

(Thanks to all the players who uploaded their Egyptian architecture to the Gallery!)

All other worlds are owned by the "Sorcerer Empire," whose ancestors were wizards.

The Imperial family has built a huge castle in Del Sol Valley and is currently in its eleventh generation.

The first couple are immortal and live in retirement in a castle in Glimmerbrook.

The Imperial family has five branches that have continued for ten generations. These branches are called "Knight Families" and reign over each world.

Blue Knight Family: Lords of San Myshuno (a Sky Fitness converted into a modern castle). Advisors to the government. The lord is a human and a scientist.

White Knight Family: Lords of Willow Creek. Related to the Goth family. The lord is a vampire and oversees public security.

Red Knight Family: They have established several military bases in Strangeville and live in a military-style castle. The lord is a werewolf and the high marshal.

The Green Knight's family: Lords of Henford-on-Burghley. They run a vast farm. The lord is a fairy and a botanist.

The Golden Knight's family: Lords of Sulani. A family that protects the beautiful sea. The lord is a mermaid, and is destined to become a five-star celebrity.

What kind of relationships will the three royal families of the new world build with the royal family of my world?

I'm really looking forward to playing.
