Bernan is manservant to Learned Hallana, and apparently is a jack of all trades including being a smith. Bernan is a wiry, middle-aged man. He is married to Hergi, who acts as Hallana's maid but is also a midwife-dedicat of the Mother's Order. Both are devoted to Hallana.
Bernan was an early success for Hallana in using sorcerous healing, curing him of kidney stones by exploding the stones within his body using the power of her demon of disorder.
Bernan and Hergi travel with Hallana, Bernan to repair the cart and other items that break under the effects of Hallana's demon, and Hergi as her midwife and physician as well as maidservant.
