Despite the crude, inhospitable-sounding name, Gok-Rock (and the coastal agricultural community that has sprung up around it) is something of an oasis compared to the continent-spanning deserts and untamable rainforests that make up the rest of Chezri.
All the best names rhyme
The original name, Rugnokuzhn, translates to something like 'the sea's life-giving rocks', referring to its nature as a coastal cornucopia surrounded by barren deserts.
Over time, this became simplified and bastardised as more and more non-tilkens starting referring to it. It was then re-adopted by the people of Chezri simply because no-one else knew what they were talking about it when they spoke of Rugnokuzhn.
These days, you are very unlikely to hear the place referred to as anything but Gok-Rock unless you're speaking a local language.
