Serenica followed some advice that the Dreamer gave her, and that advice was to leave the obsidian be. She had to meet up with the queen mother, perhaps even threaten her, and negotiate another ceasefire.
The situation had just been so bad for so long and if they would have continued blowing each other to pieces – well, Serenica used Myorka's formulas to calculate the losses, and there was one winner down that path, and its name was the Black Mountain. Perhaps this was exactly what dragons wanted, to let humans subdue each other with continuous, destructive wars and to scoop up the gold of the dying and the dead when the wars ended.
Serenica shivered as she was falling asleep, but it was not about any residual sickness at all.
She was still scared of what was about to come.
