That Avalanche Has Advanced

Depict me as you wish.
I am not the one who issued,
The blindfolds and the skis...
You speed down the slopes,
To deceive you with hopes.

I came to warn you,
Of an impending avalanche.
I was the one who came brave enough...
To insist you were heading towards darkness.
And not a party to drink with song and dance.

But since I am not a skier,
You laughed at me and took the chance.
And in the midst of your 'glee'...
That avalanche has advanced!
