Pyretygers are a closed species.

Pyre Tygers are a species born from the souls of the dead, but are not malicious beings. In a world devoid of most life after a great calamity, the statues that the previous civilization placed among their graveyards sudden burned anew again and gained life, breaking free from the stone and becoming guardian spirits. Unfortunately, the people and their souls the statues were made to protect are long gone and the Tygers have since discovered their own purposes.
