I think the Faceless should be an individual with heightened intelligence and telepathy. Also, some of the titles for Emanates seem a bit too similar to some of the other titles.
Overall, I really like this addition for the topic. I've put all of these as Emanates, but all are Karzahnian (due to Karzahni's limited abilities in creating matter).
Now adding Ekimite Kal that are listed as deceased and how:
Botar (The Bounty Hunter): second-in-command to Hydraxon. Wears the Kualsi (Mask of Teleportation). Able to bind individuals with solidified energy. Slain by Makuta in the Deeproot Jungle during the War of the Brothers.
Jerbraz (The Ghost): silent watcher of Matoran society. Wears the Huna (Mask of Invisibility). Fell to his death in Kanae during the War of the Brothers.
Johmak (The Unbreaking): Able to split her body and reform at will. Slain by Kith'alh at the Heart of Artakha during the War of the Brothers.
Tobduk (The Berserker): passionate warrior. Able to feed off of anger to grow stronger. Slain by Sidorak’s Visorak Horde in the Deeproot Jungle during the War of the Brothers.
Trinuma (The Orator): spokesperson and ambassador for the Ekimites to the Makutans and Matoran societies. Wears the Mask of Charisma to influence others’ thoughts and decisions. Slain by Makuta in Mangaia during the War of the Brothers.
Also adding two new Emanate species:
Energy Hound (species): adaptive biology. Able to sense and track energy signatures.
Kratana (species): aquatic. Possess venom imbued with varying visions of the future. Tied to the Mask of Alternate Futures.
