Order of the Sorrowlich

The order of the sorrowlich is an ancient order dating back to the first age when the sorrowliches ruled large areas of Tibaeria from palatial mausoleums within sprawling necropoli. A cavalier who belongs to this order seeks to gain power over death through dark arts and attempts to thwart those who would outlaw or destroy necromantic practices.
=== Edicts ===
The cavalier must prevent the destruction of the undead whenever possible, nor does he willingly travel with those who would destroy them.  Whenever the cavalier attacks an undead, he is shaken until he attempts to subjugate it or until combat ends. While the cavalier is travelling with paladins, he is shaken.
=== Challenge ===
Whenever an order of the sorrowlich cavalier issues a challenge, he gains a +1 bonus on Intimidate checks against the target of his challenge. This bonus increases by +1 for every four levels the cavalier possesses
=== Skills ===
An order of the sorrowlich cavalier adds Knowledge: Religion, Spellcraft and Disguise to his list of class skills. An order of the sorrowlich adds half his cavalier level to diplomacy and opposed charisma checks made against undead creatures.
== Order Abilities ==
A cavalier that belongs to the order of the sorrowlich gains the following abilities as he increases in level.
==== Subjugate Undead (Ex) ====
At 2nd level, the cavalier gains an extraordinary ability very similar to a necromancer’s ability to command the undead, using his sheer force of will. As a standard action a number of times per day equal to his Charisma modifier, the cavalier may command undead within 30 feet. Undead receive a Will save to negate the effect. The DC for this Will save is equal to 10 + 1/2 his cavalier level + his Charisma modifier. Undead that fail their saves fall under his control, obeying his commands to the best of their ability, as if under the effects of control undead. Intelligent undead receive a new saving throw each round to resist his command. He can control any number of undead, so long as their total Hit Dice do not exceed his cavalier level. If an undead creature is under the control of another creature, he must make an opposed Charisma check whenever their orders conflict.
==== One of Us (Ex) ====
At 8th level, the cavalier is healed by negative energy and harmed by positive energy as if he were an undead creature.
==== Excommunicate (Ex) ====
At 15th level, whenever the cavalier challenges a creature capable of channeling positive energy or laying on hands, the target must make a Will save (DC = 10 + the cavalier’s level + his Charisma modifier) or be unable to channel positive energy or use lay on hands for the duration of the challenge.
