Raqqa

Raqqa, also called Rakka, al-Raqqah, and ar-Raqqah, is a city in Syria located on the northeast bank of the Euphrates River. The Hellenistic, Roman and Byzantine city and bishopric Callinicum (now a Latin Catholic titular see) was the capital of the Abbasid Caliphate between 796 and 809, under the reign of Caliph Harun al-Rashid. With a population of 220,488 based on the 2004 official census, Raqqa was the sixth largest city in Syria.

During the Syrian Civil War, the city was captured in 2013 by the Islamic State of Iraq and Syria. ISIS went on to make the city its headquarters in Syria in 2014. As a result, the city has been hit by airstrikes from the Syrian government, Russia, the United States, and several other countries. In addition, ISIS has destroyed most non-Sunni Muslim buildings.

Raqqa in "Interlibrary Loan"
In 2017, Hafez ibn Abd-al-Rahim brought a copy of the Necronomicon to Ar-Raqqa, ISIS' headquarters. Here, two men, Khalid and Ibrahim attempted to cast a spell to attack the United States. However, the spell went wrong, unleashing a creature that killed all those present and effectively destroyed the center of ar-Raqqa.
