Noting the sudden arrival and precipitous drop of Waylan, carrying a slumped figure he can only assume to be their recovered ally, Morevek clicks his heels together, darting and rolling away from the cluster of demons. Freed from the imminent threat of retaliation, he murmurs words of spell casting, and makes a throwing gesture toward them, causing a burst of blinding, glittering dust to explode within their ranks!
