In the land of Aviontix there are ruins. A lot of ruins. There are many sand buried cities, king’s tombs (They were a very religious people, focused upon their leaving to the afterlife), and huge statuary. However, Aviontix was a kingdom so long ago, that everything has been looted. (Figure there has been a whole historical epoch or two since then) There might be a hidden tomb or something somewhere in the lands, but it is unlikely. This does not stop people from selling maps to them all the time.
If the adventurers are smart, they can solve this riddle and get the information they need.
To be used for the final encounter, find the final treasure, or anything that needs to be hidden away better then normal. Typical “who the heck would ever spend the time making it” but it is fun and a mental challenge for a change.
Then suddenly all your body paralizes and you hear a voice echoing in the distance "seems like another rat has been lured to my maze," this voice was terribly cold but playfull, "come on you are not already planning on leaving, the fun has only begun."
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.
