Created by an archmage called Savrille in an age long past. It is a major artifact that has the power to summon and control red dragons.
Dragon Summoning: The rod can be used once per day to summon 2,500 Hit Dice of Large and Huge red dragons. The summoned dragons remain for one day.
Dragon Domination: Dragons summoned by the rod are automatically dominated, as per the spell Dominate Monster. whoever holds the rod dominates the dragons. The domination effect has a duration of one day. Red dragons asked to do something against their natures can make a Will save (DC 30) to resist the order and break the hold of the domination effect. Obviously self-destructive orders are not carried out.
