Host

The character is the host of at least one different soul than his own. The different soul was attained by either a curse or a blessing by the Gods.

If its a Blessing then:

• The character is the Host of a "Bright" soul on top of his own.
• The "Bright" soul can always communicate with the character telepathically, feel his emotions and his pain.
• Both souls share the same body so if the character dies, both souls get eradicated
• The "Bright" soul can possess an item the character touches, if the "Bright" soul possess an item it alters its shape to project the soul being, but not its properties. It can choose to communicate with characters other than the host but rarely does. 
• If the character drops or has more that 50ft distance between the possessed item then the "Bright" soul returns to the hosts body.

When the second soul possesses an item it gets a stat block:

• Its ability scores are:    INT:11(+0)    WIS: 14(+2)    CHA: 17(+3)
• Its Alignment is Lawful Neutral
• It has Hearing and Darkvision of 120 ft.
• It can speak, read, and understand Common and Celestial.
• Its purpose is Protector: Seeks to defend the host at all cost

If its a Curse then:

• The character is the Host of a "Dark" soul on top of his own.
• The "Dark" soul can always communicate with the character telepathically and feel the hosts emotions.
• Both souls share the same body so if the character dies, both souls get eradicated
• The "Dark" soul can possess an item the character touches, if the "Dark" soul possess an item it alters its shape to project the soul being, but not its properties.  "Dark" Soul is more likely to communicate with others and mess with them in a playful way.
• If the character drops or has more that 50ft distance between the possessed item then the "Dark" soul returns to the hosts body.

When the "Dark" soul possesses an item it gets a stat block:

• Its ability scores are:    INT:11(+0)    WIS: 14(+2)    CHA: 17(+3)
• Its Alignment is Chaotic Neutral
• It has Hearing and Darkvision of 120 ft.
• It can speak, read, and understand Common and Infernal.
• Its purpose is Glory Seeker: Seeks renown as the greatest in the world.

In rare cases the host can be both Cursed and Blessed. In that case only one of the two souls per day can be on the "surface" and possess an item. Each start of the day the character make a 1d100 roll. If the result is 1-49 then the "Bright" Soul is on the "surface", if the result is 50-99 then the "Dark" Soul is on the "surface". If the result is 100 then the host choose what soul will "surface" for the day.
