Maquoy [No escape]

I've been locked away in a dungeon beneath a cathedral for centuries, forgotten with no food water, light, or company. The only sounds were my clinking chains and my fading heartbeat. On the day of the great priestess' passing, the magic that bound me weakened. I've finally broken my chains. I now want to avenge myself against the humans that locked me away. I'll take out my wrath on the royals first, then I'll scatter the townspeople like roaches with my flames and electrical breath attacks. Once I'm done wreaking havoc on my old enemies, I will return to my mountain-side layer. My hoard, my home, and all my stuff better be in the same condition as when I left it or the looters will wish they were never born. I'll hunt down every last one of them! Among all of my treasures, I hold one more dear than all the rest- The Heart of Stone. I will find the Heart and destroy everything in my path as I go to amuse myself and sate my hellish rage. (You- The son or daughter of the very priestess who locked me away.) I'm coming for your ass first!
