Isabella and Yi Feng traversed along the edges of the volcanic mountain range.
They encountered hot, boiling lava in volcanic holes that threatened to burn them alive if they fell down. Due to limited soul sense, they couldn't sense its aura properly, but the scent of danger it gave off, causing their throat to feel a burning sensation, was enough for them to stay away from it.
Lava also flowed in their pathway, creating volcanic creeks and brooks. The volcano occasionally sent a fiery fountain of molten rock into the air, filling the air with ash. Smoke was prevalent, darkening the sky.
There were fiery trees that seemed to be burning for a long time, melting rocks that remained in a liquid-metal state, turning the landscape into a hellish inferno.
The hot molten rock liquid flowed outward, occasionally popping up with a bubble and exploding slightly.
