Blue Cloaks

Grivon was really not convinced by what Sam said. But he made his subordinate perform the soul extraction and his face changed immediately because the soul was not there.

Someone already did a soul extraction on this one and that means, someone is here before or someone really killed this person and took the soul. 

Every time a person was killed like this, the Gaja clan members thought it was a virus or some other microorganism as they experienced this a lot of times.

The Mari clan due to Sivan's great exploits in this field managed to make this almost a daily routine. They always send a new variant they obtain from the research to the Gaja clan almost like it was their testing grounds and the clan members are like their test subjects.
