Hi Raze!!!
Sorry it's not that clear. Hmmm... the zodiac, all twelve are together working for the same goal of restoring the balance in whatver world needs it.
A zodiac's special ability works as a kind of job for them. Scorpio is the zodiac assigned in destroying most of the enemies etc. so elryde's character is a werewolf, she has werewolf abilities plus the scorpio ability. She will become extra strong and extra effective in killing things. Does that help?
In the IC, the Diwata summons us and we start killing the corrupted human, or purifying them through Virgo.
