The high ranking priestess was named Tsurumi. She had been serving the shrine maiden for a long time and it turned out that she was actually familiar with the giant elder. Kitsune had already told her why Elena was getting invited so she was curious how Elena knew about the giant elder.
Elena told her the story of her trial for the gates of Valhalla. It turned out that the giant elder had not contacted the Inazuyan Archipelago for more than a few centuries so they were not aware that he had managed to become an elder of the giants.
Tsurumi looked happy after learning that the giant elder was doing fine. She wanted to tell Elena about how she had met him but there was not any time for that.
While listening to Elena's story, they had already reached the room where the shrine maiden was about to meet her. So she told Elena that she would tell her the story at a later date.
