Callirus was a famous Ravnos of the Roma string of the Clan. Although he was not born a Roma, he became soon one of the most distinguished members of this line.
Born in Spain, Callirus grew up with nothing but the cons that earned him his food. One day, he managed to fool a merchant into talking so openly over masters of blood and unlife that Callirus inmediately assumed that the merchant must have been a vampire. Afterwards, he made it his lifegoal to deceive and trick others of the undead. He managed to attend the courts of Elysium without ever being embraced, tricked various Kindred into believing him to be a full-blooded vampire and left astonished and enraged beings behind when they found out that they had been tricked by a mere mortal. His pranks came to the ears of the Ravnos Elder Magdra, who inmediately went on to embrace Callirus into the ranks of the Ravnos Clan. His pranks and tricks have earned him the praise of many Ravnos and as he seldom comes around with his true identity, many Kindred have met him without realizing that they have been fooled, until it's too late.
It is uncertain if he survived the Week of Nightmares.
