The Disk of Oberu

This adventure hook is designed for a Call of Cthulhu or Realms of Cthulhu setting although it could easily be adjusted for any other setting which involves magic of one type or another.

Edmund Ralfone is a respected police detective.  He is also the leader of the Cult of Hollow Earth, a group whose goals include gaining power and immortality for it’s members by way of transformation into Ghouls.  As the cult leader, Edmund is entrusted with many artifacts the cult has collected over the years including the Disk of Oberu, a black disk measuring five inches in diameter and almost an inch thick in the center, tapering down to less than a quarter of an inch along the rounded edge of the disk.  The disk also has carvings and symbols etched into its surface which are almost impossible to see as the Disk of Oberu reflects little if any light.

The disk came to the Cult of Hollow Earth with a story that it was used by an ancient arcanist to control a creature of night so dark as to be nearly invisible as it flew along the night sky.  The arcanist had, so the story goes, used this creature to dispose of his enemies by having it catch them in its grip while they slept, carrying them to incredible heights and dropping them to their death.

Edmund hadn’t thought much of the artifact until his own enemies, both within the Cult and without, became such an issue that he had to find a way to deal with them or risk being eliminated and replaced.  Edmund spent several days studying the disk and found that by setting it on the correct side and spinning it counter-clockwise while saying an incantation it could be activated.

Ecstatic, Edmund cleared his evening schedule and performed the acts to summon the Nightgaunt but to no avail.  The disk began to glow a faint sickly green but no Nightgaunt came forth.  After trying several more times, Edmund eventually went to bed disgusted.

Unfortunately for Edmund he missed two important facts in his research.  First, the Nightgaunt only appears when the summoner falls asleep, creating a conduit to the Dreamlands which brings the creature to our world and sends the summoner to the Dreamlands.  Second and more importantly, the disk must be hidden from the Nightgaunt.  If the Nightgaunt can find the disk then it is no longer bound by the summoner’s will.  Even worse, it can use the disk to force the summoner to do its own bidding while he walks in the Dreamlands.

As a result, the summoned Nightgaunt appeared as Edmund fell asleep and quickly grabbed the disk.  It immediately left Edmund’s home and flew around the city, killing two victims that night while it forced Edmund to work for it within the Dreamlands.

Now, two days later, a desperate Edmund Ralfone is looking for someone to help him “solve” the strange murders plaguing his city.  Four victims in three nights have been killed by apparently being dropped from great heights or by being eviscerated by some strange wild animal.  Edmund managed to get himself assigned to the case but doesn’t have much time.  He needs to retrieve the Disk of Oberu and take control of the Nightgaunt before his enemies within the Cult of Hollow Earth begin to put together the pieces.  He also needs to solve or at least stop the murders before his inability to do so results in having another detective assigned to the case.

Edmund approaches the Investigators (Players) with an offer of a job and a reward if they can help solve his case.  He is able to give them access to crime scenes and autopsy reports.  He is willing to pay a pretty hefty price if nightgauntthe Investigators are able to retrieve the disk.

The ensuing adventure could go in many different directions after the Investigators are brought in to help.  If they are able to quickly retrieve the disk they may be having a drink the next night to celebrate when they hear on the local news that another murder has occurred.  At that point they will probably realize that Edmund was more than he claimed and lead to their uncovering the Cult of Hollow Earth.  If they are slow to find the disk and stop the Nightgaunt things could get even more complicated.  Another detective could be put on the case and may or may not approve of the Investigators’ involvement.  Edmund’s enemies within the cult could realize what is going on and start looking for the disk themselves, even going so far as to tail the Investigators and possibly attack them once the disk is found.

There are many other possibilities that could occur as well.  Even if things go well and they manage to stop Edmund and the Nightgaunt, the Investigators are then left holding the Disk of Oberu.  It could be very tempting to use such a powerful artifact at some point in the future which could have any number of strange side-effects.  The disk could also contain other properties besides the ability to summon the Nightgaunt.  And of course if anyone else knows about the artifact, it is a safe bet that someone will eventually come looking to take it for themselves.

Achtung! Cthulhu KickStarter

If I were to make a list of the best things to possibly put into an RPG setting two things that would be way at the top are Cthulhu inspired horror and Nazis.  Achtung! Cthulhu wraps both of those into one neat package.  Modiphius, the company behind this KickStarter already has several World War II Cthulhu products including Heroes of the Sea and Three Kings, both of which we here at the Goblin Beat have been wanting to work into our achtungplay schedule.  All of the existing Achtung! Cthulhu products are available to play with Call of Cthulhu rules or with Savage Worlds using Realms of Cthulhu.  The KickStarter however is looking for £8,000 (Modiphius is based in the UK) to produce the Call of Cthulhu version of their new Investigator and Keeper guides, with the first stretch goal of £11,000 bringing the Savage Worlds version of the books into fruition.

Once fully backed the basic release will be the two guides mentioned above as PDFs as well as available soft cover copies of each book.  One of the later stretch goals will make these hard cover books and I wouldn’t be surprised to see a later goal turn the black and white books into full color, depending upon how well the project ends up being backed.  The only other stretch goal currently visible is an Eastern Front Guide but other things that have so far been hinted at include other front guides as well as adventures.  There is also plenty of room for some interesting add-ons.  I would like to see some custom wild dice and possibly even a deck of cards.  If the cover art is any indication these could be some very beautiful books. The Noir feel of the Investigator Guide is particularly well done.  There is still a lot of time left (48 days as of this post) but don’t wait too long or you’ll miss out.
