Written by Neelh, this is the movie of the book 'The Darkness Below'. She often accidentally calls it 'Into the Darkness' for no valid reason except for a quote.
"... Toa would challenge Toa in the darkness below the city ..." This is the book where Nuparu discovers a leak in the archives and goes to Whenua to stop it. The other Toa go too. But there is a mysterious shapeshifting Rahi called a Krahka who will guard her home at all costs.
A song is in progress for this.
