Value of Regret

There was a single question at the root of the problem… why had the Thieving Bird stolen his fate? Sure, the loathsome thing seemed to be obsessed with everything that concerned Weaver. But Sunny did not think that it was the only reason. 

After pondering the question for a while, he had developed a certain suspicion. He had lost the connection to the Nightmare Spell after becoming fateless, which meant that carrying the Nightmare Spell had something to do with one's fate. Perhaps fate was the medium through which the infection spread. 

In any case, the creature which now possessed his fate… would therefore possess his connection to the Nightmare Spell, as well.

So why would the Thieving Bird want something like that?
