Exploration of The Fire Temple.
At the edge of Death Mountain, you find the entrance to the Fire Temple where Volvagia waits to bestow their blessing on whomever is worthy.
My goal was to make the volcanic mountain a bit more fantastical, as most erupting volcanoes don't keep their structure, so it wouldn't be visually compelling.
A lot of inspiration was pulled from Mount Doom in The Lord of the Rings and previous Zelda Titles.
