Where i am?

From the south, a red hand gives me a key,
Rising from the depths, flames consuming me.
The key in my grip burns with a curse,
And I turn to demon, no retreat, no reverse.
"Tell me where I am, what must I do?
How can I return to the self I knew?
I hope the boss will answer my call,
If I defeat him, will secrets reveal all?"
The dungeon's gate opened, shadows appear,
Lost souls come close, no light and hope near.
Three mages, two scouts, and five warriors await,
Spirits and demons guard this place.
One step deeper, there’s no way out,
Ominous spirits whisper and shout.
Demons laugh, my fate now claimed,
I’m one of them; there’s no escape.
"Tell me where I am, what must I do?
How can I return to the self I knew?
I hope the boss will answer my call,
If I defeat him, will secrets reveal all?"
Through jagged towers, across rivers of flame,
The bridge sways below, fire dances tame.
At the great gate, a mark of fate,
I face the one who cursed me.
"Tell me where I am, what must I do?
How can I return to the self I knew?
I hope the boss will answer my call,
If I defeat him, will secrets reveal all?"
"Tell me where I am, what must I do?
How can I return to the self I knew?
I hope the boss will answer my call,
If I defeat him, will secrets reveal all?"
