Image from www.sharkwarsseries.com: The Indi shiver's name comes from the fact that they are from the Indi home waters or the "Indi ocean"
This is most likely to be in our world the Indian Ocean. This was the ocean that was ruled by Finnivus and his Indi Shiver. Besides this, not much is known about this ocean. It is/was known as a bad place since the Indi shiver held a strong foot hold and Finnivus would have any enemies killed that dared to enter the Indi ocean. When invasion time comes, half of the battalion of the Indi shiver journey to their enemies. Thankfully it often takes them a long time for them to travel that far.
