Daemon recreates the Rose cluster

"While they journeyed, the Rose Cluster’s Great Night slowly returned. The sun turned black. But this time the negative light it emitted mingled with the fiery glow from the numerous volcanoes. The mixture of black and red light was more than usually eerie. Evidently the Chi’khami’tzann Tsunoi, the daemon of Tzeentch who had created the Rose Cluster, had only interrupted the rose cycle in order to make his dramatic appearance. The cycle was now imposing itself anew on the planet’s original nature."
