DESCRIPTION
A Therivar is a snake made of energy that can slither through the air and enjoys living in technological items.  It can enhance the function of such devices.  If Aered is killed the Therivar will attempt to flee.  It could potentially be coaxed by the party into serving them as a companion creature.  If it is convinced to join them (DC 18 Charisma (Diplomacy) check) it will inhabit one piece of technology and from that point onward that piece of technology is no longer considered timeworn (if it was timeworn) and is considered to be at full charge all the time – that is, there is no need to recharge it.  The character also gains the Therivar’s Rebuke reaction.

Therivar’s Rebuke. When the owner is stuck in melee the Therivar will lash out at the attacker and cause 11 (2d6 +4) lightning damage.
