1) Spectre: black-handled two hander sword with runs on the blade. Weapon of ancient Zaz Councilor.
2) Hellfire: double bladed sword. handle is wrapped in a red cloth. Rumored to be forged deep below the earth in magma caverns. Sword can be separated easily, but only a strong inflow of magic can fuse it together again.
3) Haunting: ancient, black/red sword of unknown origins. Rumored to hold in it the souls of its numerous victims. Sometimes, when all is quiet, chilling screams can be heard by those in close proximity to the sword.
4) Mirage: metallic boarding axe. It playes with the handler's mind by creating images which aren't there.
5) Insanity: small dagger with an ornately carved handle. Used in spiritually ceremonies by Zaz priests. Those wielding this weapon are plagued by voices.
6) Rupture: Ancient sword of obviously demonic origins. Too large to be used effectively by a human, it is stained red on just about every square inch from the blood of its victims. The weak minded gain an unending bloodthirst upon touching this weapons, and must be controlled via external means.
That's all for now. Remember there is only 1 of each of these in the whole game. Ancient weapons in hidden crypts or in possession of high-level bosses. Some are ordinary weapons imbued with ancient Zaz magic (see Zaz description) after the explosion/sundering, and others have other origins.
