The Birmingham Males

I think its more that due to the harrasment, they are more careful on what they share and who they share it with. 

But ultimately. Nhenha is in a terrible condition and will be hiding a lot more now. 
Which may explain the lack of sightings but if he died in a spot thats not easily visible, they may have already missed his death. 

Often thats how these sorts of legends end. With one last sighting before eternal silence. Reply
