"What good is it for a man to gain the whole world, and
yet lose or forfeit his very self?" - Luke 9:25
For those brave few chosen to defy the dreaded Adversary, there is no greater tool than knowledge. One who would hazard the life of the Witch Hunter must never forget who he is and from whence he came.
Therefore it is common for Witch Hunters to keep a journal, so that they might be forever reminded of the past, and so that those that would follow them in the great struggle might glean some advantage from their experience.
