Storm Mountains, Horn Peak.
This place was once named for its peak resembling a horn, but now it has transformed into a volcano.
This is the environmental altering characteristic of the Dragon Lord, wherever they reside, elements and magic power will change, even to the extent of affecting nearby terrain. Horn Peak, deep within the Storm Mountains, is surrounded by desolation, originally occupied by several Giants, whose corpses have long turned to dust.
On the scorched ground wander some fire elements, slaves summoned by the Blood Flame Tyrant-Valresaaks, further away is a dangerous legendary elemental creature 'Fanatic of Sacrifice,' created by the Fire Elemental Prince as an elemental incarnation.
This is not the lair of the Blood Flame Tyrant-Valresaaks, it initially thrived on outer planes.
