Nynrah was an island in the Matoran Universe. It was home to the Nynrah Ghosts.
Like the other islands in the Matoran Universe, the Tren Krom Peninsula was created by the Great Beings. It later became the place of residence to a local Matoran settlement and was home to a De-Matoran colony.
Little is known about its general history or inhabitants.
Order of Mata Nui/Brotherhood of Makuta War
In more recent times, an army of Rahkshi were killed on Nynrah during the Order of Mata Nui/Brotherhood of Makuta War. However, as the Order was working to to destroy most of the Energized Protodermis sources in the Matoran Universe, Toa Helryx and Keetongu journeyed to the Battlefield on Nynrah to allow Helryx to use her Mask of Psychometry to scan pieces of armor for concentrations of Energized Protodermis that the Order did not know about.
