OOC:
good thorough plans and nice rolls
Barley stays next to Rodney, as he was instructed who in turn stays close to Lord Rose. This lets Barley stay in the thick of things. As the assembled armsmen reach the valley floor most stay in the trees to watch and act as the rearguard while the lords and their bodyguards, which now includes Barley, advance into the open to confront the priest.
As you advance upon the temple priest and acolytes lord Alaric loudly proclaims their presence and demands the priests either allow the assembled lords to watch and learn or halt the ritual.The priests, all dressed in dark hooded robes continue their chanting in unison. They encircle a central stone altar where ritual lines have been drawn by some means that glow in the dark.
The dark priests intensify their chanting. None of the clergy act but several of their guard step from the shadows to block the mounted nobles parties advance. Meanwhile the ritual continues causing the skies to darken further as a menacing energies bather in the center of the valley. The ground trembles, and an eerie wind stirs. Alaric and Rose try to push past the guards but several of the other nobles are hesitant to draw sword against the temple. Though the ritual had a sinister feel many mutter that is is known that the Dark Temple employs great dark power, but it has always been for the people.
Barley watches all of this from the back keeping an eye and ear on what transpires. Suddenly Barley sees that as Alaric loose his temper and try to push past the guard one of the guards in back raises a crossbow to fire on him. As the guard readies his bow Barley crushes the bow, causing it to explode in his face and draw everyone's attention to the figure. Several of the lords become enrages at this and move to support Alaric but a couple still hold back.

Inquisitor Bjornhild
Suddenly the Inquisitor Bjornhild, now dressed all in black steps out from the ritual, blocking Alaric's path.
How dare you come and interfere with out devotions. We have only worked to serve the people. And this is how you repay us?!? May our dark lord strike you down. And the inquisitor points his staff at Alaric casting a sickly green energy over the young lord. At this all sides spring into action.
Barely casts a psychic blast at Bjornhild, disrupting his spell and freeing Alaric to lead the charge. Chaos ensues. Barley and Rodney move with Lord Rose to try and close the gap to Alaric to support him. Rodney moves to keep any from engaging Barley in combat, freeing Barley to support the fight in general. Barley conjures illusions of additional men, uses his telekinesis to give the lord's men openings, heating enemy armor and weapons, but mostly he focuses on the ritual to find the high priest to disrupt the ritual.

Phantom Priest
Barley and Alaric both seem to spot the priest at the same time. At this point the rituals energies are gathering around a single individual whos form starts to twist and bulge oddly. With a shout Alaric spurs his horse to charge the priest as Barley sends an attack to separate the priests mind from his body. The body continues mutating oddly but ceases talking and moving. The brief pause gives Alaric time to close on the former priest and strike it with his sword. Just as Alaric does Barley feels a dark presence knock his power back. As the sword strikes the figure it burst into a blaze of light causing the figure to be revealed as no longer human but a shadowy form that seems to blot out all light near it. Alaric begins chanting as his sword blazes even brighter as he engages the Mostrous priest in combat.
Barley is close enough to cast spells on the transformed priest and watch the fight but there it too much interference to get closer at this time. You can either summarize as you just did or enter and use combat rules till the end of the conflict... whatever that may be
