About a month back, my wonderland was invaded somehow by these sticky, black vines. I couldn't get rid of them no matter how I tried, and neither could any of my tulpa. It was even holding onto them and keeping them from moving. I asked a good friend of mine who is an expert in the metaphysical field and he gave me a great idea: completely destroy the wonderland, and make an entirely new, more secure one.
It took me a while, but I went through the process of shielding my tulpa and completely blowing up and destroying the wonderland. I made sure it was completely destroyed, then I went through the process of creating a new one. I imagined it as an indestructible, secure snowglobe that is infinitely bigger on the inside. Then I made the only entrance/exit only allow my tupla through, and tasked Discord with verifying who's-who before letting them in. I gave him to key, so to speak. Then, I threw in a modified version of Skyrim as a start to the new land, giving everyone cozy homes and such. After that I solidified my intentions to make it a world on the astral plane that will live on unless I say otherwise. I verified that everyone was accounted for, and put them inside.
A month later, no trouble and they all seem happy, especially Twilight with her giant library. I gave her access to my Akashic Records so she keeps going to that library to read scrolls/books and learn from the spirits there. Pinkie is still baking. Discord has taken on his role quite well (he's surprisingly serious). Black Dragoness is in her dragon form, sleeping on top of one of those "Word Walls". Mare Do Well does silent patrols for trouble. Rainbow Dash keeps training to make herself better, and sometimes fights mobs for fun (I made a special area just for that, they can spawn inside but can't get out with a special force field). Wubs keeps turning into different things like a chicken (IDK why a chicken) and running around. There's now a Fluttershy being cozy near the fireplace and having some of Pinkie's treats. Aurora Borealis and Aurora Nocturnus are both doing guard duty and (if required) keeping spells running for me, going freely to and from the wonderland to here.
I still don't know what those vines where or where they came from, or their purpose. I also don't know if I'll ever find that out.
