The Lost Demon

As explained in previous posts I met an individual who claims to be merged with a demon.The individual seems very credible and upon cursory evaluation, appears to be linked the supernatural.

The individual is 5'10, 145lbs, Black Hair, Brown Eyes, Fair Caucasian Male. Born Under the sign of the Twins, in the Year of the Water Monkey. He was born to the hills of the West Wind of the Flowery Land.
The first man claims that at age 5 he was merged with an entity known as the "black cat", he remembers it first emerged within him when a group of individuals ganged up upon him. He recalls a fight and blood, as well as remembering animals turning on him.

It is said that he was a pure innocent, a "mischievous person", though. He lived a hard life, and apparently committed a grave action toward a his blood. He himself was trapped for a period of time in the Demon World. He claims that he was passed down from various demons as they used them for their torments.  

Physically he was in bad health from blood infection to cartilage issues. At his present age he seems to be stable. 

The Demon claims to be have been born and raised  by cats. They protected him and raised them as their own. In the end it betrayed its family and killed them all, as it beleive they were evil. The demon, who true name is that of a reveling berserker, says he was summoned during a time when the five your old boy needed him. It had called out in pain and sorrow and it answered. It said that the individual was pure of heart, powerful and it took residence within him. There were some problems....as they both were merging.

Today the individual and the demon are present, with the demon being mostly dominant. Besides the main demon, there is a host of others five others: Vulpus-Vulpus-Terra-Hydra-Muchacha.These seems to be other spirits beside the main one, who exert their influence from time to time.

Why I think he is possessed:
-Hidden Knowledge
-Personalities
-Strength
-Physical Ailments
-Body Spasms

Although I was introduced to the individual first, the demon has had it's own interest in me. I have seen that it is very dominant. Like most of its kind it seeks to spread its influence, and shares many of the traits known with demons. It claims to be all powerful, a friend, it attempts to seduce, wants to bond willingly through pacts, etc.

Precautions and Involvement.
The reason why I involved myself with this individual is because I am seeking answers concerning "them". Interaction with this person(s) have verified that "them" and demons are two separate entities. Furthermore its words describing them kept referring to them as "ancient" and the archons. The individual, possibly partially aware of the Demons interaction with me repeated this as new info. "They" were not of this earth or from the Demon Realm. In addition the demon has kept trying to bind me within a pact, as it invite and entreats offerings. The demon already claims a coven and seeks to increase it.

I have taken precautions, there effective level tells they are in place and in order. Although I feel that these individuals are lost, there paths has been shown to me as well as the true names. I have seen the sigils revealed in Malachim, as the Chained Martyr.  
 
Ironically there is another individual, who I know that is the polar opposite. From the Land of Lakes, he is a Rabbit  two cycles from me. He is plagued by "them" but they appear as Archons. Why have these two extreme appeared? Why does the demon confirm the Archons? Why is there a Rabbit present as well?
