Players in all kinds of infinite games know that among the many summoning items, the characters summoned by White Sign Soapstone are the strongest.
That’s because it can summon a character who embodies the full might of Dark Souls: the Lord of Cinder.
Once he’s summoned, no matter how difficult the boss or how powerful the enemy player, you can just lie back and win with him.
As for why the Lord of Cinder answers the summons of players in infinite games, it’s simple: he just wants to drag the enemies he defeated back to his own world and turn them into flames to keep the whole world alive.
