Ragnar's tribulation, as Lex recalled, consisted of a single black lightning strike that destroyed almost every protection he set against it. Over 10 billion MP worth of protective formations had barely been enough to contain its awesome might, and in a sense, it had still failed. That was because the lightning strike had caused everyone to undergo a hallucination.
While the hallucination itself was quite an experience, and provided many with a unique insight into facing tribulations, he did not want the incident to repeat. After all, many guests were either swimming, driving, fishing or doing other tasks, an interruption during which could cause serious harm. After all, there was even an area for guests to learn the dao of the sword from Qawain at the base of the Midnight Mountain. An unfortunately timed interruption could cause serious harm.
