Reborn in Flames

I hadn't been overly special in my first life. When I'd died, I'd expected nothingness - oblivion.
Instead, I rose again with the powers of a phoenix in a world of magic, monsters, and all-powerful Dragon Gods.
If I wanted to avoid dying again, I would have to use everything at my disposal.
