Banshees

Banshees (Threat Level of Mild) have been visitors to our dimension for as long as there has been recorded human history. Most of these Entities are harmless, preferring to absorb radiation from the sun before withdrawing to their own dimension (It is suspected that to them radiation is a source of energy - attempts at destruction using U-rounds only increased their threat level). Due to their mostly pacifist nature they are mostly ignored by The Various Organizations. There is also a vested interest in preserving them as they appear near Dimensional Rifts and knowledge of the rifts is of great benefit to Mankind.
==Haunting and Screams==
Some Banshees, however, for reasons yet unknown, prefer to haunt humans. There have not been reports of more then two attacks on the same person, and no deaths have resulted except for a 86 year old man in 1976 who died from a heart attack. Hauntings generally are composed of 1-3 'banshee shrieks', and are mostly audiable to the person that is being haunted.It can me assumed that they take some sort of sport or fun in doing so as hauntings have appeared recently over the last hundred years.
If you should decide to fight a banshee for whatever reason, you will die without proper equipment such as sound canceling ear muffs, P-Guns, and/or Psyk Ammunition . Regular Ammunition is ineffective as it is phased to another plane before contact. Banshee shrieks normally are only 150 decibels - in combat it climbs to 400-550 decibels and will kill you.It would be best to do what any other human would do,run.
