Delrith

Delrith is the demon summoned to destroy Varrock in the Demon Slayer quest. He is combat level 27 with 7 hitpoints and appears outside the south Varrock entrance in the Demon Slayer quest. Interestingly, he has less health than a level 3 player just starting to play, and even Imps have more health than him. This is due to the fact that he has been freshly summoned and, as a result, still weak from his movement between dimensions. The demon can only be attacked with Silverlight and no other weapon or the message "I'd better wield Silverlight first" appears. Although he is strong to a newer player, he is level 27 only because he was recently summoned and needs time to gather his strength.

History
Many years ago, during the late Fourth Age and early Fifth Age, the druids of Taverley had many stone circles built across Gielinor. At these sacred altars the druids would worship Guthix, the god that created the world. One such circle was found just outside of Varrock, the massive capital of Misthalin. For some years it stood as a beacon to the followers of Guthix.

The circle was destined to fall, however. 150 years ago, in the year 19 of the Fifth Age, the stone circle was captured by an order of dark wizards, who, for unknown reasons, sought to destroy Varrock in Zamorak's name. It was here that they summoned Delrith.

Fortunately, a man named Wally happened to be outside the gates at the time. Gripping Silverlight, the sword of a fallen knight he had discovered in the recently created Varrock Sewers, he killed Delrith with the assistance of a magical spell that he had received in a mysterious series of letters.

Although this no doubt raised tension between Zamorakians and the rest of society, the two religions would not break out in war until the year 70, when the first Wizards' Tower was destroyed by Zamorakian mages. Delrith's weakness is the sword Silverlight.

Demon Slayer
During Demon Slayer, a cult of dark wizards - perhaps descendants of the ones who summoned Delrith in the year 19 - manage to summon Delrith once more. This is foreseen by Gypsy Aris, a seer that lives in Varrock. Once the player learns of this, they begin Demon Slayer.

To defeat Delrith, the player must acquire Silverlight and the magical spell used by Wally. Once he is reduced to 0 hitpoints, he takes on the form of "Weakened Delrith" and can be banished using the incantation. Delrith is aggressive and can only be killed once.

Trivia
During the job interview in the Servants' Guild, the Demon Butler states that for several centuries he was Delrith's private valet.
