After the Battle, once the Wendigos were at last driven off :
"So..." Chrysalis huffed as she watched the armies celebrate. She stood in a tent with the other global leaders... discussing peace.
Her fear of the Wendigos, was the only reason she was considering it. Her plan had almost worked. She had turned against her 'allies' ready to conquer all the world... when the Wendigos appeared and ruined everything.
She long since thought the spirits of conflict were extinct... the now three way war was forced to end as they all united against the Wendigos. They won in the end, driving the beast back... but at what cost?
"That's it, is it? The battle is won and we forget we've been slaughtering each other for near 200 Moons."
Thorax sighed, "I don't think the world will ever forget."
Chrysalis scoffed, "Naive grub."
Celestia walked over to her, standing by her side and watching the celebration, "Forgiving, is not the same thing as forgetting."
"Changelings once lived like this," Chrysalis looked around at her children, all her children, laughing and drinking with the other races. "We embraced you... and thought you returned our feelings. We protected you and helped you... and in return you enslaved and butchered us... crushed thousands of innocent eggs... I won't make that mistake again."
Chrysalis began walking off but stopped, looking back at Thorax. "I will admit. In my need to protect you, from my mistakes, I forgot what I was trying to preserve. I now realize I can't force you to see things my way... and perhaps I should change how I do things a bit, but never forget... everything I did... was out of love for my children... for you...
"but I will finally accept you are destined to repeat the worst of my decisions... I'll be here when it all blows up in your face. See you in a few thousand years."
Post Global War :
After their defeat, The Wendigos were approached by a race of "Sub-ponies" called "Time Ponies". They claim to bring a gift from Sombra. Before offering the Wendigos berries, which come in flavors of: despair, hate, anger, violence, and fear. Which meet all the nutritional needs of the emotional parasites.
The bushes even grow in winter. So the Wendigos can farm them in the snowy wasteland of their territory.
The Wendigos may have lost their war, but because of Sombra (who convinced the Doctor to help), they gained the ability to become truly independent, without need of hurting any Sapient creature.
8 years into the space age :
Wendigos didn't have traditional family dynamics. Instead whenever they lay eggs they put them in a Hatchery where the child is raised by qualified teachers until they are a teenager. Then the child chooses which clutch they want to belong to. Each clutch is responsible for running a different task to insure the community thrives. Wendigos do not get money for this. Instead they live in a utopian society where all work for the good of the community.
Wendigos are, by nature, fierce apex predators. They believe they are the ultimate lifeform, and do not recognize other creatures as sentient, which is why they feel no issue using them for food.
Frost Bite is 5 years old and tired of constantly being teased by the other children for being so meek and gentle. He runs away and meets Tempest, who he feels he knows somehow. She recognizes something in his eyes and ask, "Grubber" but Frost Bite doesn't know who that is. Still he invites himself to travel with the pony. As they leave Frost Bite swears he could see a shadowy monstrosity in the snow, Discord, but when he looks nothing is there.
14 years into the Space Age :
Doctor Whooves arrives at Tempest's cabin in the frozen north, a few miles outside the Crystal Empire. He informs Tempest that Discord asked him to enroll her adopted son into his school. She ask what else Discord told him, and the Doctor warily admits that Discord said the foal was a newly claimed Cleric of his, a Wendigo reincarnation of The Changeling Grubber. Tempest sighes with Relief, "Thank Celestia, I'm not crazy,"
