In the end, I had no choice but to follow the mummy and the rest of the group all followed me.
The other three groups were confused about what was happening, but my group had grim looks on their faces as they recognized that this wasn't a good thing.
The fact that we were being called by this mummy and in such an urgent manner most likely meant that something had happened. If something happened, it was very likely that this was related to the mummy leader.
Right now, we wanted to stay as far away from the mummy leader as possible to draw as little attention as we could.
But now it didn't seem like we had a choice.
So we had no choice but to follow the mummy to the floor boss' room.
As we headed over, I went forward and moaned a few times, using the Suggestion skill to ask this mummy what this was about.
However, all the mummy did was shake its head.
