Bane looked at him and said "lady Serena believes they were created in Mordor. They have been running around for months growing their pack. They have doubled in size in three weeks" Bilbo blinked and asked "how are they growing in numbers?" Bane sighed and siad "it's why we are trying to warn people...it's not the creatures themselves that are the threat...it's what they carry within them that is the risk...when the Alpha is in battle and he bites any kind of creature, human, elf, dwarf or even hobbit...they will be infected or cursed and....they will turn into one of those things..with no cure to change them back...it's a fate worse then death"
