The 7 Eldritch Kingdoms

While drawing on your driveway with chalk, your 6 year old little sister somehow managed to accidentally draw a teleportation circle... Wait! That shouldn't be possible! magic isn't real... Right? Well, that's besides the point. Your sister fell in the mysterious swirling inky black portal, and your parents swore that they would ground you for life if you let anything happen to her. I guess that means that you are jumping in after her.
