The Cloudflow Empire suffered a devastating blow under the forbidden magic of the winged skeleton. Night of the Dead Spirits and Rain of Blood encased the entire battlefront of more than three-thousand yards. Under the Rain of Blood, there were only mages holding on by casting all-around magic shields, while soldiers donning all-sealing armor stood at the edge of the Rain of Blood.
The spell was known to be terrifying, not only for its powerful penetrative ability and vast area of effect, but also for the shrieks of countless spirits that were heard at the forming of a huge black vortex in the beginning of the spell. It severely distressed all living beings within.
Any warriors who were of a rank lower than swordmasters were rendered stiff from terror for a short period of time. They were slaughtered by the Rain of Blood right where they stood.
