Taienra was the only one who knew exactly how far away they were from Pirate Haven. But since that knowledge was more like instinct due to her nature as a Starry Sky Whale, it was difficult for the others to understand what she meant when she tried to explain how far away it was. Taienra resigned herself with a sigh and just told everyone to be patient instead of trying to explain further.
Since it was so far away, Taienra didn't feel like rushing and tiring herself out when she could take it easy and enjoy the trip while at the same time deepening her connection with the trees.
After the battle with the three void beasts ended, and after everyone had recovered, Toz told Taienra what he knew about the trees and what he had found out during his stay on the island. From that, Taienra expected the trees to absorb her mana and become filled with the star attribute.
