Son of the Apocalypse greets you Steamgifts (Giveaways?!)

Humble men and women of Steamgifts,
I am Umbra or "Shadow" as the tongue of mankind might know it.
I was given birth 25 years ago.
Today is my anniversary and the day I plan to end the world.
I was called Lux at my birth or "Light" as you may know and my task was to save the world.
However I was corrupted by treason, by pain and empty promises.
Now all what remains is to destroy, what has destroyed myself.
Consider these gifts: Binding of Issac and Legend of Grimrock as my last kind gesture of a dying virtue.
I'll march to war to end this world.
This theme will play and if you hear it...
Run...
NOW.
