The Faithful Illithid (his or her true name being unknown) served many masters with a diligence and neutrality that belied the reputation of the Illithid race. When, in time, fame brought too many sages, kings, wizards, and demons willing to pay even the Illithids exorbitant price, it retreated to another plane of existence where it continues its work in relative peace. But if your reputation is high enough, even a pocket dimension without entrance is no discouragement.
The Faithful Illithid still takes commissions from a variety of customers, provided the customer has the knowledge and power to reach the Illithid in its private refuge. The creature is known to employ a number of trustworthy and reliable agents throughout the planes to carry out its customers requests. No commission is too obscure or too dangerous for The Faithful Illithid.
