Based on the alternate universe fanfiction, by chedx

The first 50,000 cadets are about to graduate from the Storm Kingdom Cadet Academy and after the graduation, they will be sent into the frontiers and provinces of the kingdom or sent to reinforce the frontlines of the siege against the Crystal Empire.

Pep Berry Juice is basically a wine in this world, it's a drink that makes you happier and gives you a good feeling. Yes students in this academy are allowed to drink it once they graduate. See? The General isn't all that bad...okay she is but still..

Lightning Dust unlike the rest of the ponies, was enthusiastic about the new kingdom established by the Storm King and General Tempest, she joined the Storm army immediately and was granted the rank of "commandant" as well as put in charge of intense air combat alongside her former rival, Commander Rainbow Dash.

What would the graduation party feel or look like? Well think the banquet on Onigashima, from One Piece.

Yep, I just imagined, Lightning Dust busting a move and celebrating with the cadets she helped train for battle.
