England head coach John Mitchell wants the world champions to embark on a golden period of success, starting with defending their Women's Six Nations crown.
The Red Roses make their first appearance since defeating Canada in September's World Cup final when they face Ireland in their Six Nations opener on Saturday.
A record crowd for the women's tournament, expected to be around 75 000, will watch England chase their 34th consecutive test victory.
Mitchell believes England are ready to establish a sustained stranglehold on the women's game.
"This team has probably already built a legacy. There's an opportunity to build a dynasty, but we're going to have to earn that right," he said on Friday.
"It also won't hurt if we don't get it right occasionally. Over the next two years, there are a lot of factors that will distract our girls along the way."
Mitchell is already setting his sights on the next World Cup in Australia in 2029.
But he warned his senior players that their World Cup triumph is not a guarantee of selection in the future.
"I'm really open minded around selection. I'm really looking to see how people compete within the group and see how they handle that," Mitchell said.
"The experienced girls that experienced the World Cup have had different exposures since then, which is fantastic.
"But it's important for them to be able to manage that noise and make sure they are where their feet are."
