The common grave. This term is also called "Hell."
Hell does not mean what the Catholic's teach. Back when Christianity was hijacked, the Roman Catholic Church would speak lies and use "Hell" as a concept to control the people through fear mongering. Although, Hell itself is just another term for the common grave.
The True God, is a God of love, not hate. The Bible states His name is Jehovah, and His son is Jesus Christ, who sacrificed Himself so that His precious blood could pay for our sins, and so that repentant sinners could be saved by the price Jesus paid. Jehovah hates the sin, but loves the sinner. He desires they all repent, as He wants as many saved as possible. Hell does not exist as the Catholic Church likes to teach.
The False God, the God of this wicked system of things, is a God of hate, and his name is Satan. In Heaven, he was known as Lucifer.
He does not have literal horns atop his head. Pictures that show this are symbolic. I believe it is supposed to be representative of arrogance and/or pride. I thought I should clear that up for you.
Horns in the Bible represent power, authority and rulership... kingdoms etc...
