AR 1217-06-10 The group is asked to subdue the Master and return him to Golden Eagle Clan for Justice
Just before the group left, the three kings called the group together one last time and went over why they felt it was very vital to subdue the Master and bring him to the Golden Eagle Clan for trial.
They asked that the group keep this quiet for they did not want to spread panic.
The Kings and the high clerics felt that it was highly likely that if the Master died somewhere without some special precautions taken that there was a high chance that he would come back in some manner. Either the lich lord would turn him into some type of undead to cause more havoc, or if he has made a pack with Asmodeus (they know Nails worships him and Nails works for the Master) he might be turned into some type of devil or demon, or he could turn into a type of undead that would allow him to seek the justice he feels has not been handed out yet. This could mean he could come back as a lessor devil, demon, ghost, ghoul, shadow, specter, wight, wraith, or revenant.
This is something they want to prevent at all cost. Please take great care to not kill the Master.
