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.

Unique Charms

• Dark Gauntlets

First, the ability to manifest a pair of dark gauntlets.  To do this, visualize
dark gauntlets gripping my hands.  To end the effects of this charm, visualize my
hands unbound.

• Gives Strength Boost

This boost is 2 str per 1% of bond strength, but caps at 200 including buffs from other sources. Thus if you have 150 points of strength buff from another source, the gauntlets will never buff your str by more than 50. You will also need to remove/reequip your gauntlets to have the strength buff update. -- Marcosy

Second, the ability to command a friendly creature over which your familiar is
sovereign to undertake a specific action.  You can command multiple creatures at
once in this manner.  To do this, concentrate on commanding your follower or
followers to undertake the desired action.

Third, the ability to tame creatures over which your familiar is sovereign.  To do
this, concentrate on taming the creature.

Fourth, the ability to channel spiritual energy from your familiar to yourself.  To
do this, concentrate on channeling spiritual energy inward.

Fifth, the ability to convert spiritual energy into more refined forms.  You sense 
that this bond is enabling you to acquire entropic energy with this ability.  To do 
this, concentrate on channeling my spiritual energy into the desired type of energy.

Sixth, the ability to channel spiritual energy from yourself to your familiar.  To
do this, concentrate on channeling my spiritual energy outward.

Seventh, the ability to enable oneself or others to see in the darkness.  To do
this, concentrate on enabling yourself or your target to see in the dark.

Eighth, the ability to fly.  If you already have wings, this charm will increase 
your maneuverability.  To do this, think about flying.
