What i mean by this is that when players are progressing towards the 'king' (or realm creator) capabilities, they should have a good idea of how the tools work and what to expect when they finally get to creating stuff.
Right now the tools are somewere between user friendly and your run of the mill editing tools for games like this (very unintuitive for casual players) As someone who loved the idea of creating a campaign for the shadowrun returns game it just ended up being waaaay out of my league to get into.
Chaos's realm tools on the otherhand are just accessible enough for me to bang out some realms, though some of that might have to do with the scope of the game (you don't have as many things to tweak as a full fledged rpg game) being incorporated in an ingame gui helps alot.
Although I feel that i'm in a bit of a niche, somewere between casual player and hardcore "i'm going to design custom maps/campaigns" or what a modding community might look like.
Nothing really specific to suggest but i hope you find a way to introduce players to the realm tools, perhaps when realms possibly get reworked would be a good context to advertise them to would be realm designers and make them more accessible.
