The swift bell rang urgently, pealing seven short chimes, and after a few seconds' interval, it rang another seven times, three rounds in total.
Tirian listened attentively to the noises outside the window. He heard some talking in the hallways and rushed footsteps on the square outside.
The mid and senior-ranking priests were responding to the bell, arranging protection at key points and preparing for the vigil. The highest-ranking figures in the cathedral probably had already gone to a secret sanctuary, ready to participate in the saints' assembly.
Tirian was not a man of the church, but he had lived half a century and understood the rules quite well. He could discern critical information from the frequency and repetition of the bell—it was the summoning bell for "Listening." It was an invitation to a meeting issued directly from the Tomb of the Nameless King, and the situation sounded quite urgent.
