Yeah the cards portray the traveler as good and bad. Ive read all the cards i have and until the book of sorrows it was clear it had its own intentions. But see how the story unfolds in my opinion it seems the traveler isnt good or bad but uses the populations it touches to its own needs in which case seem to be to slow down the hive/darkness which is determined to stop it. Until they actually say fk the zombie ball or all hail the ball, i think its ment to leave the actual purpose of it open.
