So yeah, to reiterate what people have said, Vetex is probably planning the story progression, islands, etc for Nimbus Sea. A long time ago, Tech confirmed that he and Vetex already cooked up the entire storyline for Nimbus Sea. It’s likely right now, he’s just fine-tuning the story progression, also including islands and story quests.
Main story isnt everything in the Nimbus Sea, there’s also side storylines and quests, each one still having some importance to the overall exploration, worldbuilding and even to the main story. Then, he has to make the islands where such quests will be on.
Every quest, not just main story, has importance, and even more so in the Nimbus Sea. Vetex revealed Order of Aesir isnt gonna be the main focus in Nimbus Sea, meaning he has to also consider making some Order barons or even High Lords accessible through side storylines, which is kinda implied in one post he made introducing the Order. And we also need to remember there’s also some other side storylines that are set up for Nimbus Sea such as the Captain Arwald quest.
Oh, and don’t forget bosses as well. He has to plan ideas for movesets and stuff.
There’s a lot of planning and fine-tuning to do, quests, islands, story, bosses, etc. So for now, Vetex is in brainstorm mode alongside Tech.
Though, I personally don’t mind him getting breaks. I mean, tf, he keeps updating the trello notes at 1am-2am several times in his timezone, worst cases are up to 4am. He works full time on AO and man, he deserves some good breaks every now and then. Also, its thanksgiving.
