The Abandoned Reef is a large reef to the southwest of L'ghorek in the Abyssal Depths. The reef's appearance is much like that of a reef that has died, white coral with very little life present. Only a rare spirit beastcrab, Ghostcrawler and a few crab hatchlings are the only wild life found here.
Although a mostly empty subzone, herbs and mining nodes still spawn here.
Speculation[]
This article or section includes speculation, observations or opinions possibly supported by lore or by Blizzard officials. It should not be taken as representing official lore.
It seems to be a leftover from the beta of Cataclysm, perhaps developers planned Abyssal Depths to be of a certain size but ended up never needing this subzone at the "end" of the zone. Its name is quite fitting.
It's possible that what the Old God is doing to L'ghorek is affecting the area. Even Deepfin Ridge, in the area closest to L'ghorek, appears to be dead.
