The sins, yes I know of them, the Sins are beings manifested from the evils of the people in this world. They are not evil by nature though and are more human than anything. As for how many there are, of the ones I know exist, there is Lust, Vanity, Gluttony, Wrath, Greed, Envy, Pride, and two other that I am unsure of...The ones who have unfortunately been taken by my counterpart are Lust, Vanity, and Gluttony as for Ira I am unsure what fate befell them. The shards are the Sins cores that give them power and hold their personalities. If a shard is taken from a Sin a number of effects may take place but a temporary cease in existence is assured.
