Rama stared straight at the 'relic'. He immediately knew that whatever the relic was, it was something from the evil realm. Or is used for clearly evil purposes.
Plus the fact that the Order comes directly here for it. He was one hundred percent sure that whatever the relic was, it was something related to his vision. The vision about the Blood Moon Ritual.
'I have to destroy it. But how?'
Rama turned to some of the Hunters who were here. Even if he could get rid of those Hunters temporarily, Rama wasn't sure that he would be able to destroy that relic.
Realizing that there was nothing else he could do here for now, Rama decided to return to the surface. Maybe he could find the way if he thought for a few moments. Or asking for help from his friends.
Once he finally returned to the surface, Rama walked out of the alley where he had turned as if nothing had happened.
