Necrovarus also featured in the 2015 Hallowe'en event, installing a copy of the Ectofuntus in the Grim Underworld. He would also hand out his notebook on the mechanics of the Ectofuntus and prayer in general.
At some point in recent history, when the vampyres of the Sanguinesti region rediscovered the settlements north of Mort Myre, they immediately imposed blood tithes on all the villages and lordships, including the thriving Port Phasmatys on the north-east coast. The residents' numbers dwindled as the blood tithes took their toll, at which point Necrovarus arrived from the east, claiming he had had a vision of a great power source to repel the vampyres. He had the villagers delve beneath the port, and they discovered a large reservoir of ectoplasm, from which they built the Ectofuntus. This resulted in a magical barrier around the port, which Drakan and his vampyres were unable to cross, keeping them at bay. During the artefact's construction, one of Necrovarus's disciples had turned against him before the project was finished, and fled.
Although the Ectofuntus worked perfectly, it had a terrible side-effect; the townspeople gradually lost the will to live, and all of them eventually died - even Necrovarus himself perished in the end. The townspeople became ghosts and found themselves unable to pass into the afterlife, trapped by Necrovarus's powers, supplied by the Ectofuntus. Some townspeople accepted this fate while others ended up as tortured souls, haunting the vicinity of Port Phasmatys. Necrovarus himself, now a ghost, ruled the town, aided by the Ectofuntus.
In 169 of the Fifth Age, one of the residents of Port Phasmatys, Velorina, enlisted an adventurer's help to stop Necrovarus's scheme. Upon finding out, the priest dismissed the possibility of danger and threatened the adventurer to stay away. However, they found the disciple that had run away, now an old woman, and with her help they were able to find and translate the book of Haricanto in order to enchant a ghostspeak amulet to be able to issue a single command to ghosts, after an unsuccessful attempt to diplomatically coerce him into allowing the townsfolk to pass on through a petition.
Using the enchanted amulet, the adventurer once more confronted Necrovarus, commanding him to let any soul who so wishes pass on to the Grim Underworld, and he was forced to comply, surrendering to the adventurer when threatened with a worse fate. He remains at the Ectofuntus with his disciples today, but has little influence left in the town, although some of the ghosts still support him.
- In the Ghosts Ahoy quest, when using an enchanted ghostspeak amulet, one can command Necrovarus to do an impression of a chicken without discharging the amulet. In his impression he says "Cluck cluck squuuaaaakkkk cluck cluck" then "I think I've laid an egg..." Also using this amulet, he may be convinced to tell you a joke without losing a charge. The joke he replies is "Knock Knock, Who's there, Egbert, Egbert who?, Egbert no bacon".
- Necrovarus' name comes from the Greek prefix necro-, meaning dead, and indeed may be a play on necrovirus.

- ^ Velorina, "Ghosts Ahoy", RuneScape. "Necrovarus told us that he had been brought by a vision he'd had of an underground source of power. He inspired us to delve beneath the town, promising us the power to repel the vampyres."
- ^ Velorina, "Ghosts Ahoy", RuneScape. "He showed us how to build the Ectofuntus, which would turn the ectoplasm into the power he had promised us. Indeed, this Ectopower did repel the vampyres; they would not enter Phasmatys once the Ectofuntus began working."
- ^ Velorina, "Ghosts Ahoy", RuneScape. "During the building of the Ectofuntus one of Necrovarus's disciples spoke out against him. It is such a long time ago I cannot remember her name, although I knew her as a friend. She fled before the Ectofuntus took control over us, but being a disciple of Necrovarus she would have been privy to many of his darkest secrets."
- ^ Velorina, "Ghosts Ahoy", RuneScape. "Little by little, we began to lose any desire for food or water, and our desire for the Ectopower grew until it dominated our thoughts entirely. Our bodies shrivelled and, one by one, we died. The Ectofuntus and the power it emanates keeps us here as ghosts – some, like myself, content to remain in this world, some becoming tortured souls who we do not allow to pass our gates. We would be able to pass over into the next world but Necrovarus has used his power to create a psychic barrier, preventing us."
