The Shifting Winds Of Lahar [Inktober Prompt #24 Dizzy]

Introduction:

The massive volcano Gol that towers over the rest of the Tazalt Mountains is known to spew toxic fumes, smoke, and other matters of debris all around Lahar as it vents its fury.
Unfortunately, the winds in Lahar do not stay constant, and with that, the toxic cloud of gasses that spew from the Volcano can be shifted anywhere.
Unwary travelers who get caught in such a gust of wind will find themselves choking on their breath, growing dizzy until they eventually faint and die from the toxic gasses.
