Hashr is the boss of the Sand-Swept Tomb dungeon and the Corrupted Sand-Swept Tomb dungeon. He also plays a significant character in the storyline of the Desert region. With this, he appears in the Desert Royal Residence Secret discovery.

"Hashr was born around 1400 BP to the Emperor, an extremely powerful figure who ruled over the Desert for many centuries, with an empire known as the Desert Empire. He was the Emperor's 26th son, amid a myriad of other sons that he had. At one point, he traveled beyond the walls, exiting the Desert and exploring the rest of Wynn. There, he learned that the rest of the world was vibrant and magical, unlike what he had thought before: he was likely taught that the Emperor was like a God, the only individual who could harness magic in the entire Desert.

Outraged that the Emperor's world was a lie, and wanted to save the people of the Desert from him. Hashr traveled back to the Desert and met with his father in his royal residence. After a short quarrel, Hashr jumped at his father and assassinated him, taking his sceptre, the source of his magical power. However, the Emperor had placed a curse on his sceptre, and as soon as Hashr usurped his power, it created a great sandstorm that raged on for years and buried the entire empire under the sand.

Hashr, realizing how immensely powerful the sceptre actually was, hid it in the Temple of Swords so that nobody could find it. His subjects would then bury him within the Sand-Swept Tomb and use magic to seal the entrance to the tomb, to make sure that he would never leave. Then, when a bandit group called the Creden Tibus found refuge in the Temple of Swords and discovered the sceptre, they took it for themselves and hid it again, as they didn't want it to fall into the wrong hands." (from: Hashr, Wynncraft wiki) Later on, the player finds this sceptre and opens the tomb.
