Mons Igneus

Aerugino came wandering from far away lands, caring not if he trespassed into lands not his own. His strange looks interested King Red Arenae, whom welcomed the intruder at his side, for he was as ruthless as him. Aerugino quickly gained a reputation for his disdain of all, and his love of himself only. Still, he was an excellent right hand lion to the king and he was home within the brutal Perfugas of the Desert. While his solitary ways were unknown to the pride, his cruel and uncaring ways against all whom opposed him made him a loved addition to the bloodthirsty pride.
He brought with him great interest for the unusual and the strange, and soon, multiple new mutants were welcomed into the Perfugas.
But as Aerugino grew older, less and less members believed he had any chances to become king, for he wasn't a prince. Until the Second King, as he retired, proclaimed Aerugino as his heir, chasing away his own son. Thus, the intruder from far away became the Third King of the Perfugas, and laid claim on the Volcano of the Great Desert. Aerugino walked the crater of the Volcano under the watchful eye of the Sun and the approving gaze of the spirit of the First King. As the ancestors roamed the lands, Aerugino took his place under the scorching Sun, and as the ancestors sought his help, he cared not. For he cared only for himself, and now for what his pridemates could offer.
As Aerugino saw the end approaching, he took for himself the name of the Great Volcano in the hopes of insuring his eternal remembrance. For he is the King of the Perfugas and he deserve to be worshipped just as the savage Huntresses worship the uncaring Volcano. And as his weakening body will be cast in the fiery guts of the mountain, his spirit will become one with the burning stone of the Volcano. And the wanderer from far away will forever become part of the ruthless Desert.

There's no pity under the Sun. Only blood and fire.
