Since warrior suffixes are passed down through families in the Warrior Bloodlines universe, to begin with, there will be a list of families and their suffixes here. Refer to this list when choosing parents - if your character's parents are roleplayed by another member, check their suffix here. If your character's parents are NPCs, choose a suffix that has not been taken yet.
