Arakis's zombie problem went largely ignored, because it was believed that the Shai-Hulud (sand worms) would effectively dispose of the undead walkers. Unfortunately the problem grew until the roving herds of sunburnt ghouls threatened the flow of spice. While observing one of the great reanimated masses over take a Harvester from the safety of an ornithopter, an Imperial Zoologists noted that the sand caked flesh eating revenants walked entirely without rhythm.
Shortly after receiving this report the Bene Gesserits claimed to have a solution to Arakis's hellish resurrections. They asserted to the agents of the great houses that the worms could be drawn to the walkers using an ancient sonic weapon. According to the sisters, exposing the zombies to an antediluvian ballad composed by the great master M. Jackson would force them to step in time.
One of the PCs comes across a magical ring that grants some power but has odd aura as if cursed. Yet this curse is different than the standard curse. When the PC puts on the ring he/she suddenly feels married. There is now an illusionary woman, who he/she cares deeply for but who is also always very critical of the PC. The wife is demanding of attention and constantly giving the PC directions. The PC wearing the ring is the only one that can see and hear the bride. The curse can never completely be lifted. Even if the PC takes off the ring and somebody else puts the ring on; the PC will still be visited by the ex-wife at least once a month. During this visit she will demand money and apologies.
Cold Comfort is a long-sword of star-steel, its blade giving off a wan, blueish light. Its grip is wrapped tightly in snow-serpent hide, and its pommel bears a single opalescent gemstone.
This blade is enchanted in such a way, that whoever wields it, begins to fall completely and irrevocably "in love" with the weapon. This love does not manifest itself as the expected reverence and bond formed between any warrior and his weapon, but as a deeper, truer love, one has for a soul-mate of the same species! The longer the wielder carries Cold Comfort the stronger and more disturbing this love becomes, and only the most powerful of magicks can potentially break the sword's insidious spell. The blade's owner will even speak to and coo to the weapon, convinced that the sword understands and returns this epic love.
If the blade's wielder somehow loses the weapon or has it taken away, they will become inconsolable, and will predictably go to "ends of the earth and back" to retrieve it at any cost. Such is the weapon's curse that even separation from it does not damper the feelings the owner has for the sword. Legends tell of several distraught and mind-addled knights who even years after losing the blade, still wander the country-side searching for their lost love. And woe be to the "new lover" if and when they find him or her.
