Eren didn't recognise the man, but it was impossible for him to not know the identity of the person that the second statue was based on.
He had not seen that woman before ever since he entered this body, but Ren Necroline was different. Not only had he seen that woman but he had also met that woman.
The statue depicted Mist, the Western Overlord and also the person who seemed to hold the key for him to unlock his cultivation that was sealed.
She was the woman who Devourer warned him about the most, telling him to stay away from her. At the same time, she was also someone that sent him as a spy, not realizing his real identity.
He was surprised to see that there was another person whose statue was placed right next to Mist's statue. No, his statue was one step ahead as if the man was the leader and Mist was just a follower.
He wasn't sure if it was because the first statue was that of a man, but it was also made bigger than Mist's statue.
