In Overlord Vol 4, Ainz is the central figure. He is the one who has to face all the challenges and make important decisions for his territory.

I'm not entirely sure about brand - new characters specifically in Vol 8, but existing important characters like Ainz Ooal Gown continue to be central. His actions and decisions drive the plot forward.
One important new character is from a previously unintroduced race. This character has a special connection to the magic of the New World and their appearance shakes up the existing power structure. They interact with Ainz's forces in unexpected ways, leading to some tense and interesting situations. Another new character is a young prodigy in a certain type of magic who catches the attention of Ainz's subordinates and may play a role in future developments.
One important character introduced could be some of the new leaders of the local factions in the New World. They play a role in the political and military aspects that Ainz and his forces interact with. For example, there might be a new king or a powerful general.
