The House of Arceuus (pronounced "Arr-KAY-us") in Great Kourend are wizards who commit themselves to studying magic through the Dark Altar, a mysterious altar whose powers extend to life and death, expanding their Magic abilities and producing runes for the region.

There is a fairy ring that can be reanimated by paying Trossa, located north of the Arceuus Library, a one-time payment of 80,000 coins. The code, CIS, can only be used after Trossa reanimates the fairy ring.

A majority of those who reside in Arceuus are former humans who, through the power of the Dark Altar, are able to achieve immortality by moving their soul from their mortal body into an incorporeal one. Their souls are freed from the mortal bodies in the crypt below the church, and take on the incorporeal form commonly seen among Arceuus residents.

The art of runecrafting has been known by the Arceuus since at least 150 years before the wave of visitors from the mainland arrived. However, they were unable to create law runes, explaining the lack of teleportation spells around Zeah.

However, a book titled Transvergence Theory documents the differences between runecrafting in the mainland and runecrafting in Zeah. While the mainland uses talismans to teleport individuals to another dimension, runecrafters in Zeah use energy that emanates from the ground near the Dark Altar to change the essence.

Arceuus is closest to the northern reaches of Zeah, and is the first line of defence against the Wintertodt, a mysterious entity that brings along with it extremely harsh cold.

Transportation[edit | edit source]

There are several methods of travel:

Gaining house favour[edit | edit source]

WARNING: If you already have 100% favour in another House, ensure you have spoken to the respective House's Architect to lock in the favour. Gaining favour in another House before speaking to them will make you lose favour in that house!

The Arceuus architect is Arcis, who is found east of the bank.

Earning the favour of the Arceuus can be done by assisting the Arceuus Elders with expanding their knowledge, seeking your own dark knowledge, mining Dense essence block and using the Arceuus spellbook. Once earning 100% Arceuus favour, players are able to runecraft blood and soul runes at their respective altars if players have level 77 and 90 Runecraft respectively.

Assisting library customers

A player in the Arceuus Library.

Because of the Arceuus Library's unhelpful librarian, Logosia, customers in the library are having trouble finding the texts they seek. Players can speak to Sam, Professor Gracklebone or Villia to search bookcases for books or scrolls around the library for them. To help narrow down where to search, talk to Biblia, the assistant librarian found at the top floor of the library. She wanders around the northern parts of the library.

Note that if a player is required to find either of the books Transportation Incantations or Soul journey, it is recommended to read them, as doing so will unlock the Teleport to Kourend spell and the Bear your Soul miniquest respectively.

Once the text is found and returned to the respective NPC, players are rewarded with a book of arcane knowledge and 2.5% favour. Speak to another NPC looking for assistance, as the NPC you already helped will be busy reading the book/scroll you gave them.

Seeking dark knowledge

Once players reach 20% favour, they can speak to Horphis, an Arceuus wizard, who will ask players to collect dark manuscripts found within the library. Players can again speak to Biblia to narrow down the location of the dark manuscripts and the books. This is by far the fastest way to gain favour, It's possible to gain 100% favour within 30 minutes.

Multiple manuscripts can be obtained without consistently returning to Horphis. Each manuscript given rewards a book of arcane knowledge and 5% favour.

Mining dense essence blocks

Once players reach 25% favour, they will be able to mine dense essence blocks within the dense runestone mine, located east of the Dark Altar. Make sure you bring a chisel as well as a pickaxe and have level 38 in crafting and mining.

Players can turn in dense essence blocks to Clerris, rewarding 0.1% favour for every block handed in.

General tips and additional information

  • As this involves a lot of running, players should wear lightweight gear (e.g. full Graceful) and bring a few Super energy or Stamina potions.
  • Most players spend most of their time earning favour at the library since it is the fastest method, which takes about two hours to gain 100% favour from zero.
  • Always speak to Biblia, who roams the corridor on the top floor, for help with finding books and manuscripts.
  • At 20% favour, it is strongly recommended to focus on manuscripts while doing book runs along the way only if they pose no inconvenience or entail going out of the way.
  • Stockpiling manuscripts saves time, but it helps to turn them in if going to past Horphis.
  • You can stockpile books and scrolls by returning to the location of the most recent request and grabbing another copy after handing the original in.
  • Even while remaining on the same world, the locations of books and manuscripts change after a while.
  • Sharing the locations of books and manuscripts with other players allows you to find them much more quickly. The best world to do this on is 310, the Kourend Group Activity world.
  • You can plant mithril seeds to mark the location of books and manuscripts that you find. This makes it easier to find the same shelf if you return to retrieve a second copy of a book; the flowers also serve as a clear marker of the location of books and manuscripts for other players.
  • If you plan to reanimate ensouled heads, it would be wisest to start reanimating at 60% favour. This is because reanimation also increases favour within the house and is a more efficient way of reaching 100% while simultaneously training prayer and magic.
