The Heruirulilango - The Negative Kissed

One - I can smell your sweat, your heart, your blood, & your flesh.
   I hunger for none of these
         I hunger for your life
All those moments of time, your first kiss, your first love, all those precious moments will be ours

         They lurk in the fringes of space, waiting in the darkness where the black clouds of the outer darkness have passed in the night. They are the products of the negative planar energy that lurks in the coldest regions of space that pass through the cosmos.
They are more then simple undead, they are an undead hive mind linked by the planar energy matrices that pass through each body. The sum makes up the whole & as they eat they experience your very soul through your flesh. The hungry ones become their victims for a time. An hour, a day, it doesn't matter for they are you for that time reliving your every good & bad facet of your lives. All your secrets become theirs & while their hunger is held at bay they share all of the good bits of your memories. They laugh, they cry, & for a time they are alive once more. They become colorized with your life & wish to experience that feeling again & again.
That is until it all simply fades away...

 There are thousands of alien thoughts that buzz through that hive mind & as the energy fades it is replaced by its negative once more. The cold hunger of malice eats away at the soul as well as the flesh. The hunger is all & there is the  strength of the desperate & angry there.
Yet these creatures are harvested by another race. The Irtulat hunt these spawns wherever & when ever they can. The race is a silicon based humanoid race & totally devoid of emotions & yet they can extract these qualities of life force that the  Heruirulilango have consumed. They track each orbit of the rare black holes that project that special energy & wait patiently for the coming of such an event. Patient & immortal they take their time as the events unfold.  

 -

They simply collect  the Heruirulilango  within the holds of their space craft & render them down. The're equipment allows them to experience each succulent thought, every high & low as if it was their own. Yet they are more then mere explorers    of experience. They are information brokers par excellence. They move through each & every thought using equipment to record all of the dirty little secrets of the universe only to sell them to the highest bidder or use the best ones themselves. 
 There is no truth that they have been known to allow or move these cosmic events themselves. No truth what so ever.. 

Negative planar event taking place near a black hole  creating the perfect  events for a Heruirulilango  affair  

Use your favorite zombie stats for this encounter.  The Irtulat  are far too paranoid to meet with anyone & only act though primitive robotic agent bodies.
