I notice that as we progress, the story telling always refer us players as "he" or "she" or "the one and only". So assume there is only one WoL ? However in actual game play, we are many. We do party, hunt, chat, and sell. And sometimes during the story when we fight some boss, we also split into many also, despite in the story there were only one of us and a NPC.
Then again, when Warrior of Darkness showed us, they come in team, so it look like there were more than one WoL on their world. Then why we only fight them alone with the NPC and not seek other WoL in this world for help? Do other WoL exist at all in the lore?
