Investigation

Beelta ignored the delegation of duty that occurred. It is understandable that the porcupine demon would be reluctant to risk his life. A contract doesn't need a willing agreement for it to be effective. Only a written agreement is needed and that can be acquired by force or threat to life. So her contracted subordinates aren't highly motivated.

The weird demon is lucky she doesn't want an actual threat to his life. If someone refuses to sign a contract, she will kill that demon and use him or her as a lesson to encourage the others to sign. She had made an exemption for the weird demon because a chance of progress for her had to be taken delicately or she might lose it forever. Now, look where being soft has led her to.

They finally sent a little beholder to inspect the situation. The beholder is the size of a fist and the clone of one of her subordinates. The clone will serve as an extra eye to the beholder and he will inform them of the situation.
