Most likely this new 2D Style is going to be obtainable from the Summer Clan Wars Event personal Fame Points Shop.

Ghost Stallion –
“It was our last battle. Our warriors had fallen, and the fate of the islands would be decided at any moment, when suddenly a green cloud appeared on the horizon. My first thought was, ‘The alchemists are at it again’. One of the survivors shouted, ‘Aurora Borealis!’, but the smoke was moving too fast. They were horses. With no riders. At full gallop, beautiful and… Terrifying. They brought with them a horrible cold, their eyes were glowing in the dark, their metal barding shimmered with carmine in the moonlight, and the rhythm of their shoes portended approaching justice…
That’s all I can remember from that night. Even though I shouldn’t think about it. Among the thousands of worlds we ride in, there is none where it is worth remembering our earthly life. And yet, I am happy to think that the islands will always be peaceful.”
