So, a few days ago (16. April 2016) aired the episode "Gauntlet of Fire" (S6 E5).
It introduced a new dragon character: Ember.

Today I looked at the feature box, and 6 out of 7 (!) of the new stories contains Ember.
It doesn't happen very often a new (background) pony dragon gets that amount of attention in such short time.
And we don't even have an Ember character-tag (yet). I hope it will come soon.

I'm curious how long this will last.
