Ackster and the others could only look on in awe and horror as they saw the ramifications of Makkel's fire. Makkel had burned away all of Mbelg's luck. So, when he was surrounded by people, each with their own fair share of fortune, he experienced what would happen if everyone around him was lucky. He had no defense against their luck and what it was trying to accomplish.
Whenever Mbelg moved with the intent to cause harm to Makkel and the others, their luck would roll to try and make that not happen. Each time their luck tried something, it succeeded. Mbelg was caught in a web of the fortune of his soon-to-be killers.
With such a disastrous fate looming against him, it didn't take long before Mbelg lost the last of his energy and turned into a tiny, glossy black marble. Mara and the others helped him along. But when he finally lost the ability to take shape and regressed into the very core of his existence, Ackster stepped forward.
