probably not but Im sure we could be given a general summary of the differences
# 605 - The party must track back to save two Vanguard, while Glenn continues the raid alone. He finds Vanguard and Porre troops discussing what to do with a small Mystic Den claiming to be fed up with Kasmir. The three Vanguard captains have differing opinions, and Glenn must side with one of them:
# Renault’s option: Help Porre raid the village
# This option will show Glenn giving into his distaste for the Mystics, and ravaging the village. Porre will give you thanks for helping them. You get attack-oriented armor/accessories. In 1005 A.D., tensions with Porre will have backed down somewhat, while Medina will become unfriendly. Montcrief will have been reprimanded for starting hostilities and demoted to Lieutenant General.
# Luther’s option: Prevent Porre from raiding the village
# Porre will express incredulity at this course of action and will send forth some soldiers that Glenn will defeat. The Mystics will thank you and give you a reward (magic-oriented armor/accessories). In 1005 A.D., however, you will find Porre to be much more hostile to you. Montcrief will be promoted to High Commander of the Armed Forces of Porre.
# Roget’s option: Declare neutrality
# This provokes a dismissive reaction from both sides. When it's over, the Mystic and Porre fighters will have been eradicated to the last man. The corpses are available for looting, and thus you obtain far more items than you would with either of the first two options. In 1005 A.D., both Porre and Medina will be unfriendly. Montcrief will be normal.
