Just some vent art... I suppose. I like the way Discord came out.
Crystals are hard, and cold. They are stone and rock. But they are also organic and slowly grow over time.
Also yes, That's a symbol for Fluttershy's element there in the middle.
Not really sure what's going on here beyond that.
Background is a bunch of textures:
Thanks so much for the feature EQD Fluttershy stared in horror at the crystals growing out of Discord. "Discord, what happened? What is this?"
"What? This?" replied Discord non-chalantly. "Oh, it's nothing to worry about. I'm just dying. That's all."
Discord suddenly let out a yell and doubled over in pain as another crystal emerged from his back. Fluttershy quickly flew under his arm to help support him as he started to sway.
"When did this start?" she asked him as she helped him to the couch.
"About two days ago, though I've could've been infected months ago. Years even," he said, gingerly lowering himself onto the couch.
"Infected? Is this some sort of sickness?"
"Of a sort. It's called the Deus Mortalis virus. The Spiritkiller. Right now, the magic in my body is crystallizing at a rapid rate and sending me to a very, very painful death. Overall, it's not an experience I'm relishing right now."
Discord flinched and clutched his side. Fluttershy looked at her friend with a sad expression on her face. "Discord, why didn't you say something sooner? I could've done something to help."
"Because you couldn't have. I've been trying everything to stop it or slow it's progress, and nothing has worked. Besides...I didn't want to you to worry..."
"I'm going to get Twilight," said Fluttershy, flying over to the front door. "She might know some way to cure it. Trust me, Discord, I will make you better."
"And if you can't?"
Fluttershy stopped and turned back to Discord who was sitting upright and staring intently at her.
"It's better than doing nothing," she replied "I'll be back soon." And with that, she left.
"Nkk." A crystal started protruding out of Discord's palm. "I hope you're right, Shutterfly..."
