There was so much one could learn from decades prowling through the mortal and demon realm, and one of such was the true depth of a bond that was dependent on trust and complete reliance on another.
All demon blooded creatures, demonic beasts, true demons and the most rare divine beasts, a part of the beast race that had almost reached extinction,
All of these possessed the innate ability to establish a lifetime bond of servitude to a chosen master by offering a portion of their life essence.
This bond would tie master and beast in soul, spirit and mind for all eternity, it could never be broken except in death.
Originally, this bond was meant to be a symbol of the greatest trust and the truest loyalty but centuries innumerable had gone by since the East continent was established,
And just as many centuries since the races had been divided to respective realms, the times had changed and so had the people.
