Howdy, sorry for the super late reply; it's been a busy July. All of the info I have regarding existing realms is on the realm map, so it does look like SE SC is a tad on the bare side. Since you're looking to start a realm, I'd highly recommend checking out the
Belegarth Starter Kit. It has a ton of guides, tutorials, and how-to's for everything from foamsmithing to realm management. If you have any questions about how to go about things, feel free to shoot me a message. Realm management, recruitment, and retention is my passion.
