With a low and hoarse tone, Green guided a creature from this distant Foreign Domain to acquire his Devil's Contract but not sign it.
Getting such an apparently beautiful contract would make any creature wary.

In other words, the Grand Sorcery of Sacrificial Descent was only halfway completed.
Thus, Green immediately began trying other means of communication.
