The Arceuus House (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 House 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 the Arceuus House 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 House residents.
The art of runecrafting has been known by the Arceuus House since 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.
The Arceuus House 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.

Gaining house favour
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. To do this you must have started the
Architectural Alliance miniquest by speaking to
Hosa. Otherwise gaining favour in another House before speaking to them will make you lose favour in that house!
The Arceuus House's 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% favour of the Arceuus house, players are able to runecraft
blood and
soul runes at their respective
altars if players have level 77 and 90
Runecrafting respectively.
Assisting library customers

A player in the Arceuus House Library.
Because of the Arceuus House 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 House 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.
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.
House benefits
- At 20% favour, players can access
Thyria's Wares.
- At 60% favour, players can speak to
Tyss next to the
Dark Altar to switch to the
Arceuus spellbook, which contains reanimation spells that are intended for use on
ensouled heads for
Prayer training.
- At 100%, players can make
dark essence blocks, made by using
dense essence blocks at the Dark Altar, which can be then used with a
chisel to create
dark essence fragments, used in
runecrafting
blood runes and
soul runes, which also require 100% favour.
- At 100% favour, players can create
magic tablets to Arceuus spellbook teleports by using the lectern found in the
Ouditor's house.
- At 100% favour, players can speak to
Tyss to obtain an
Arceuus signet, which are required in building
dark altars or
occult altars within a player's
Achievement Gallery.
