I am the Ice Tower Tesla. I was once used by the gods. Dowsing flames, I obey the light.
I have become a mountain of ice. I will conceal all.
I have evolved. I will entrap all in the ice which surrounds me.
A self-reconfiguring freezing weapon created by the gods to seal away a disastrous fiery beast. In the intense battle with the fiery beast, as it grew larger and its armaments stronger, it built around itself an indomitable frozen defense. With this power it managed at one point to completely seal the beast, though later an angel came and released him. The weapon of the gods wasn't concerned with good and evil, and lived only to follow commands.
