DM: *PREVIOUSLY, IN EQUESTRIA...*
Discord GM: Oho, this is gonna be good!
DM: Discord had succeeded in turning Ponyville into the chaos capital of the world. And, foreseeing that the Elements of Harmony might rebuild their friendship, he put some extra protections in place. Discord turned Ponyville into a nexus of random alternate realities, making it nigh-impossible for anyone to hunt down his throne world and take him down. However, the Elements of Harmony recovered and regrouped faster than Discord expected. Thus, they were able to localize and isolate Discord's chaos magic to just Ponyville. In giving up their hometown, they bought the rest of Equestria a little more time.
Discord GM: Wha– Now hold on!
Rainbow Dash: BWA-hahaha!
Discord GM: This is ridiculous. Pulling one over on *the* Lord of Chaos? When he has had a thousand years to anticipate every move?! Surely Discord would have noticed that he's been sequestered away in a city-sized cage by now!
DM: Oh, Discord would have noticed very easily, and he could have probably reversed it. But that's only IF he took his victory spree of chaos shenanigans outside of Ponyville's city limits. Outside of the protective dimensional labyrinth he'd built for himself. Out where he would be more vulnerable to getting turned to stone by the Elements of Harmony. Why risk that when he can wait for them to come to him and have all the fun he wants in the meantime?
(beat)
Discord GM: Clever girls.
A thousand years aren't all that useful if you spend them in suspended animation, unable to know any of the developments of the civilization and people you're going to try to conquer/subdue. He could just as likely have been broken out into cyberpony land and instantly contained in some technodoodle with little effort, that's the extent of what he doesn't know he doesn't know. Well, the player does know, but that's hardly a way to justify a character's superiority.
Was Discord unaware during the thousand years, or was he just physically contained? It's been a while, but my impression is that he was aware of what was happening in Equestria, just unable to interact with it.
To quote the Irish song Lord Nelson, about the IRA's destruction of the Nelson Pillar in Dublin:
And then in 1966, on March the seventh day,
A bloody great explosion made Lord Nelson rock and sway
He crashed, and Dan O'Connell cried, in woeful misery,
"There are twice as many pigeons now will come and sit on me!"
Also?
"You can't outthink me because my character had one THOUSAND years to scheme, you can't outpower me because I am Literal Chaos and I can deprive you of your wings, horn, and oh, just turn you against each other with a snap of my fingers." is BORING and unfun unless you get off on lording over people.... in which case it's extra unfun for the people you're lording over.
I figured it was at least a few weeks in-universe. The wedding, the rejuvenating the elements, RaNdOm EnCoUnTeRs. Kind of like how Bill in Gravity Falls screwed around for a few weeks before actually trying to leave town/earth
I'm curious how this will go down when we reach the end of this arc. Discord-DM isn't malicious, but a few of his comments & reactions make me think he's a little bit of a sore loser. I don't think he's going to throw a tantrum or anything - you can't be a good DM if you can't handle players eventually beating your puzzles, and the comic has indicated that he is a good DM, despite the Mane 6's discomfort with his play style. Still, his reaction here & his earlier reaction to Fluttershy figuring out his plan during their last session make me wonder if he's going to protest or get a bit huffy as things progress.
Not sure what will happen, but I'm eager to find out!
Still, for a plan improvised pretty much on the fly, this scheme holds up better than I expected.
