Vain, ancient and not entirely of the same plane upon which it was discovered, Lorveer's Mask has wandered across numberless regions and zones of consciousness and experience, and it will tell you all about it, if you prove yourself worthy of its hard-won wisdom and guidance. Fashioned from seamless panels of hammered and burnished Plattnerized brass over a thin layer of lead and lined with a speckled violet and gray fuzz, the mask is very comfortable, once it allows itself to be worn. The single eye-gem takes some getting used-to, but it provides excellent depth perception, despite being cyclopean--literally--the eye-gem is a crystallized cyclope's eye. At least that's what the current lore surrounding this mask asserts.
There is a growing body of information regarding this particular relic-mask. Mostly this consists of warnings and advice along the lines of what former wearers wished they had done way back when they had the chance. Even the most scathing reviews and critical assessments of this mask agree that the thing is quite good at what it chooses to do, what it is interested in doing, and completely terrible at all else. Willful, stubborn and highly opinionated, Lorveer's Mask tends to be egotistical and very restrictive, always setting conditions and requiring negotiation for every little thing, unless one can overcome its vaunted ego or break its will. Many have tried, few have succeeded. Those that have made the mask a partner or colleague have gone on to impressive things, but then they also left the mask behind once they got there. Many modern scholars consider entering into an arrangement with this mask to be a means to an end. One should probably have an end in mind before taking it up. Or not.
No one claims any real expertise in dealing with this uppity mask from beyond. The most common practice is to use the thing for a specific task, rite or ritual, then hand it off to some other
Upon encountering Lorveer's Mask for the fist time, each person involved should perform a Reaction Roll as though they were a potential retainer. A negative result causes the Mask to remain inert and disinterested in the character. Any further attempts (limited to one fresh attempt every 1d4 days) will require some sort of sacrifice or offering before-hand. All subsequent failures at this Reaction Roll will result in the Mask using one of its powers to cause mischief (30%). There is a cumulative 10% chance of it teleporting away with each failed attempt.
On a successful Reaction Roll, Lorveer's Mask will deign to allow the character to wear it. The Mask grants the wearer a number of advantages, all of which it will point out in excruciating detail over the next hour or so. It will also specify the ground-rules as it desires things to be from now on. The wearer must then either accept the mask's dictates, or attempt to re-negotiate. Every sacrifice or offering given to the mask nets the wearer an additional +1 on their Reaction Rolls for one day.*
Surrendering the mask to another, potentially more worthy wearer (someone who rolled a good Reaction Roll), allows the former wearer to relinquish the mask with no ill effects. Should the new host fail their Reaction roll, the mask will inflict 2d6 damage on the current wearer and deny them use of the mask's powers and abilities for 1d4 hours. It cannot be removed during this time, however it can be removed afterwards. Each time the mask is removed incurs a -1 penalty on subsequent Reaction Rolls. Every hour the mask goes without a host wearing it also incurs an additional -1 penalty to Reaction Rolls. If the mask is abandoned, it will Plane Shift away...but it will never forget, nor forgive the one who abandoned it.
*Appropriate sacrifices for Lorveer's Mask consist of feeding it werms, worms and anything similar. Each HD of worm-like thing fed to the mask will placate it for an hour. It will also accept serpents, with some complaining and reluctance. It will not touch grubs. No one has discovered why it is reticent in this regard, at least not yet.
