One time I was playing as a wolf character in a pack. We were wandering around, looking for a decent spot to rest and chat. Then, we stumble into a den and find two characters. Let's just say the oldest one in our pack reported them, and the others ran away, pretending they saw nothing.
Another thing that happened, which was like, beyond creepy:
There was also one time me and my friend were whispering each other. I walked away from the computer for a moment, then come back. She whispered me, saying that some guy with the user '0' was whispering her. I forget what '0' said, but my friend seemed pretty freaked out. She then said to come to the map, because '0' was there, and she was freaked out. Out of curiosity, I decided to go along with it. It was probably just a joke anyways. I switched characters and went to the map to see what the alpha (my friend) was so concerned about. She's just staring at nothing, freaking out and whispering me about this '0' guy. Pretty much, she said '0''s character had the same name as his user. He looked identical to her character in every way, aside from the fact everything was pure black, and I guess she found out it's gender as she kept referring to him as a he, but she might've just been randomly saying 'he', not sure. Anyways, pretty much, I couldn't see it. Other members of the pack came online, and they didn't see it either. At one point, in whisper, she said that the black wolf was right in front of me. Confused, I walked forward. She said the characters were touching noses at this point. Out of amusement, I kept my character still to see what would happen. I forget the rest of what happened, but I do know that at one point after everyone logged off, I went back online, went back to where my friend last saw this '0', and my game crashed. I was freaked out, and I just went to bed.
