Apparentaly a guest said: About your pony ghost zone. In DP show you can see unicorn, pegasus and "alicorn" (Fright Knight's horse) themed ghosts so why would you turn all ghosts to "alicorn like" as you put it? I can see some powerful ghosts like Pandora, Nocturne and Clocwork as alicorns but wouldn't "normal mlp pony" to be a more natural form to other ones? If you are going to use DP ghosts, of course. And if you want to make them special, how about widigo like appearance?
But of course this is your story so naturally you are the one making the decisions. These are just my own thoughts.

To this, I say: Yeah, I know that. But they're not true alicorns - not the weaker ones. You see, Alicorn magic is still new to the GZ. And only a few who didn't die as alicorns actually have an affinity to them. As for the horse themed creatures in the show, I say "To HAY with them!" (MLP reference). They won't be in here. The ghosts who ride them will be in the tale, but their mounts won't be. Unless somepony has an idea for the mounts besides dragons and magic?
