Dark Age: Mage
Lord Kasimir was reputed to have a magical tapestry that allowed him to persuade others to follow his directives. This was hinted as being the source of his power and how the Polish nobility fell to sending sacrificial tithes to the Witch Innesca.
The tapestry is a family heirloom and requires the blood of an ancestor to activate.
Magnus claims the tapestry will probably have to be destroyed with an expenditure of quintessense.
