The Ba'Shan's Spiders are a type of spider that were the result of breeding a male Ba'Halen's Spider with Madam Octa. They were named after Darren Shan by Seba Nile who first found them. The spiders were moved from Vampire Mountain where they lived to a tunnel in the Future wasteworld where they were placed for Darren and Harkat to see by Mr. Tiny.
