Dead March

The [Sepulcher Song] was an active enchantment that consumed more essence depending on how great the number and power of the corpses stirred into a murderous rage by it was. An Ascended could wreak a lot of havoc with its help…

But not nearly as much havoc as Sunny, an Ascended Tyrant whose soul was augmented by Neph's flame, could.

Influenced by the angry melody he was playing, most of the bone orchard was already in motion. Some of the giant skeletal remains were too severely damaged to assemble into the semblance of a whole creature… but there were plenty of dead abominations who could. 

Some of them had clearly been aquatic abominations in the past. Nevertheless, they slithered and crawled forward in the throes of bloodlust. Some of them seemed to have been able to walk on land. Those were moving much faster to kill something, as quickly and as cruelly as possible.
