Angor only had several hundred crystals left after visiting the bookstore. He didn't believe he had enough money to buy magical thread even if he could find them, so he simply left Moshi's Street and headed to Champagne Road.
On his way, he thought about making some more money since he would soon need it.
He still owed Sunders 150,000 crystals. The debt was due about half a year ago, yet he never had a chance to get to it since he was forced to travel through Fairy World. Sunders did not mention the debt yet because nobody knew whether Angor could return from the garden challenge alive. But now that Angor came back, it was time to talk about money problems.
Angor once read about how "Nightmare Domain severing" worked. Sunders spent lots of wizard-level materials in order to stabilize Angor's own piece of Nightmare Domain. Added with Sunders' fame and great skills, 150,000 was a pretty cheap price.
