When Twilight Sparkle had the magical surge that cemented her place as Celestia's student, the amount of power she released not only hatched a baby Dragon, it brought forth something else. Something that shouldn't exist any more.
Something that has Celestia worried.

A fluffy puppy.

[Despite the gore tag it's rather light on that, and they have yet to make a lewd tag and there's a bit of that.]

Season two is live here, Season 2

This story is a sequel to Rot

After the events in 'Rot', Twilight Sparkle has finally come to terms with her new self. Can she control her new powers? Can she ever have anything close to a 'normal' life again? And what happens when Discord's past mistakes come home to pass judgement on the 'new' Princess of Friendship?

From father to son to grandson to great-grandson, on and on down through the centuries, Celestia has continually found love and comfort from a singular line of remarkable stallions. For a thousand years, she has been romanced and bedded by a succession of lovers from what may very well be the most charming, suave bloodline to ever exist.

Then Luna returned from the moon...

A 'Know your Star' story; only with your favourite ponies getting unneeded hassle and lies told about them. Won't this be fun? Probably not... But hey, everything can't be seriousness all the time, so let's take a load off and just pester some ponies, and Spike for good measure.

The never ending adventures of Know Your Mare march on and on and on.
