Irem, The City Of Pillars:

(Arabic: إرَم ذَات ٱلْعِمَاد‎ Iram dhāt al-ʿimād; an alternative translation is Iram of the tentpoles), also called “Irum”, “Irem”, “Erum”, “Ubar”, or the “City of the pillars”, is a lost city, region or tribe mentioned in the Quran.

Rub’ al Khali:

The desert is 1,000 kilometres (620 miles) long, and 500 kilometres (310 miles) wide. Its surface elevation varies from 800 metres (2,600 ft) in the southwest to around sea level in the northeast.[4] The terrain is covered with sand dunes with heights up to 250 metres (820 ft), interspersed with gravel and gypsum plains. The sand is of a reddish-orange color due to the presence of feldspar.

There are also brackish salt flats in some areas, such as the Umm al Samim area on the desert’s eastern edge.

That is not dead which can eternal lie,
And with strange aeons even death may die.

Abdul Al-Hazrad:

Likely a mistranslation of “Abd al–Azrad“, which would read “The worshiper of the great devourer”, this name is assigned to the original author of the Necronomicon (Kitab Al-Azif). The “Mad Arab” wrote his tome sometime before his death in 738 AD.
