Orb of draconic influence

An orb of draconic influence was a powerful magic item which allowed a dragon to influence the behaviors of other dragons.

Description
The orbs were spheres of dark green obsidian decroated with intricate geometric etchings and gold filagree. They employed the same fundamental magic as an orb of dragonkind.

Powers
A dragon could use an orb to subtly influence the behaviors and dispotitions of all dragons within. Usually, the weilder would concentrate on a single command or feeling they wished to impart on all nearby dragons, such as "attack" or "friendly."

An orb also afforded some protections to its weilder: its magic both blocked scrying of any kind and discouraged dragons and other members of dragonkind from attacking the weilder.

History
Orbs of draconic influence were created by dragons in order to be weilded against other dragons. Some sages proposed a divisive suggestion that the orbs could be used to cause a so-called "Dragonflight," the phenomenon wherein a large group of normally solitary dragons of various alignments would suddenly decide to behave in synchronicity.
