Glimmer, Fallen, Hive, Cabal, Hex are all Bungie trademarks broad enough to include everything from books to Halloween costumes and films as of March 11th. What this has to do if anything with the former Halo studio’s recent reveal of its shared world shooter Destiny is anyone’s guess, at least for some of the terms mentioned.
Cabal and Vex seem to be Destiny’s antagonists, seemingly very much in line with the Bungie school of enemy names that brought us the Covenant. Fallen has also made Destiny-related appearances as spotted by Gamespot UK in press materials as a type of cyborg race who wear fur for some reason.
