From the 2nd world of FIRE, smoke ink is the shadow self of 7lore.  He was created originally by the beast of sound.  Some think INK created him while others presume it was the INK tree itself that created smoke ink.  He is responsible as the messenger that first gives 7lore his choice of gaining the ability to bring the dead back to life with one catch.  He must take a life for every life he raises.  Smoke ink is a shadow spirit heralding from the FIRE world.
