From Vanguard Wiki
The Kojanese Archipelago is covered by dense jungles, and is often considered a continent due to the total land mass of its many islands, architecture, and the fact that new players can choose to start the game here. The heroine of Kojan is Eila.
Kojan is "...to the east; inhabitants of the tumultuous jungles of Kojan fiercely battle encroaching otherworldly fiends."
 Official Description
"The island chains of Kojan are steeped in mysticism and shrouded in ancient tradition. From dense jungles which have swallowed entire cities to the mist-shrouded mountains hiding forgotten monasteries, the Kojani lands are rich in history and offer ample opportunity to an adventurer quick of wit or sword.
Great artifacts lay undisturbed in the ruins beyond the imperial city of Tanvu where Kojani Humans and Half Elves work side-by-side trying to restore the glory of their city. With powerful battlements and crude domiciles, the port city of Martok is home to cunning Orcs and Goblins who are willing to help any adventurer part with their gold. Hidden away in the jungle, the Wood Elves and their Raki allies have created a sanctuary, Caial Brael, where they hone their skills against the savage dwellers of the inner island."

 Level Progression
Right now the progression of Kojan is from 1-20 overland, with the Tomb of Lord Tsang supporting players into their mid twenties. The level 45 mobs you see guard the entrance to one of our highest level dungeons - The Fallen Kingdom of the Ulvari - which is for players from 45-50+
Unfortunately for the levels 25-45, you'll need to hit up Qalia/Thestra and possibly some of the islands inbetween.
If you want to be your best against the Ulvari though, you won't want to miss any of the quest lines involving The Tomb of Lord Tsang =P Teclisen
Can't really go into concrete details - though I have a strong suspicion we'll be adding more Kojanese content at some point. Kojan was certainly scaled back more than the other two continents. And though we're definitely happy with how the amount of Kojan we did get in turned out, there's plenty of lore, story, and hopefully even space in the world to expand on it for sure. Teclisen

"Kojan is a large archipelago and we also consider it a continent because of its size and distinctive style, look, and inhabitants relative to Thestra and Qalia." - Aradune Mithara
