Familiar

This is a spherical region of opalescent indigo darkness that pulses in a
slow, menacing pattern.  You recognize this as an cadagion, a kind of energy
being composed of entropic power.  Ordinary weapons do them little harm, and
they are capable of using the kinder emotions of their attackers against them. 
It sparkles with a miniscule faintly shimmering opalescent indigo dweomer
aura.  It appears to be composed of a few thin streamers of darkness and a few
thin wisps of shadow.  It has a webwork of sparkling light within and around
it.  It looks about two fifths of a dimin across.  It is in good shape.  Its
movements are very quick.

Requirements

Some degree of Ownership

Bond failure

You sense a slow hunger that quickly turns into disgust emanating from the
shadow, as if it was expecting to find a matching hunger from you that does
not exist.

Imagined bond

You imagine forming an empathic bond with cadagion via archsymbiosis. You imagine what it would be like to have a deep bond with the cadagion, and you feel a distinct echo from within it. You experience feelings of envy, coldness, hunger, and covetousness. You experience visions of devouring darkness. You experience astral visions of flows of entropic energy.

Bond "Quirks"

• Cadagion's do not register exploration when carried, this appears to be due to Paravision. This can possibly be a problem when taking them through dangerous new areas or into areas where following is problematic.
• While there will eventually be an Ownership skill boost due to increased Spec Access, this will unfortunately not increase your Keep capacity.

Boons

• Adds Ownership to all attack, dodge and deflection ratings.
• Adds Intimidation to damage ratings.

• It fires random shots off based on your affinities.
