This is a very tribal, Bedouin-sounding track featuring a leitmotif that was used in previous Dune games. It sounds like you're about to embark on a great adventure, like riding a sandworm?
Speaking of sandworms and how to ride them, in the world of Dune the local people of Arrakis known as the Fremen are masters of riding the giant beasts known as sandworms. In order to ride a sandworm first you must lure it using "thumpers". The sandworms are attracted to the vibrations caused by the thumpers and once the sandworm surfaces the lead worm-rider uses a hook to pry the worm's shell open to expose its soft inner tissue to the abrasive sand. The worm is then irritated and turns its body upwards which is how the rest of the Fremen ride the worm.
