Siren's are a species that have always been heavily connected to the Phoenix' groups. Their innate magic for guiding is within a similar vein to the flame magic within a Phoenix; both are intrinsically connected to life and planar barriers. The phoenix are the barriers themselves, where as Sirens are free to move between them at will, as long as a 'thread of fate' is connecting at least two souls between them. With the barriers gone things are a little more confusing for the species, though they seem to be doing okay.

Threads of Fate are connections between the sparks of people. A Siren can at the very least feel these connections, and use them as a guide for guiding their Master or Mistress. For example, they can see if two people are linked via history, feelings, interests and more in order to define the best path for the pair to take; whether that is becoming friends, lovers, enemies, etc. They can of course be wrong about this, though it is rare as they spend most of their life reading these connections and will only comment when certain or are pushed. Most Siren's excel at secretarial roles within courts due to this, and are mostly seen under the employment of Kings or Courts of Law.

After the cataclysm, many Siren's became lost or confused; what were once easy paths to follow had become a tangle of webs. Most have taken refuge in the area they now call home, attempting to relearn and redefine their job in life. Those that lived with Hosts have run away for the most part, or died from being driven mad. Very few continue to live away from the rest of their species' home, with most of those being held captive.
