>JTY: The second Arcane Journal will be released alongside Miao Ying and the individual releases from the Cathayan Battalion, but there are no other unrevealed units scheduled. It’s a very narrative journal – we focus on how Chaos is affecting Grand Cathay and what makes the Storm Dragon decide to travel to the Old World. We discuss Cathayan connections between east and west – hinting at the antagonisms between the Jade Fleet and the Elves of Ulthuan – and the continuing war in Westerland.
Bratty dragon is going to test the so called "dragonships" of the elves.
