Talk to Faraus in Vareth's Infirmary and he will mention that he can't find his text book and that it is probably at the Olacion Order. Talk to Kain, get the book back to Faraus and he will be added to the Friend List.
Born into a family of doctors. He studied medicine at the Olacion order until he realized the imprecision of the art. He entered the mage guild to try to make medical treatment available to the general public. Basically a gentlemen, he can become arrogant to those he regards as his inferior.
Faraus is the first water elemental character you can recruit. His stats are average to low with the exception being Defense. He is a long ranged character so he will stay out of the way. Depending on preference, it should be noted that unlike Stone Javelin, Frozen Sword does not knock the enemy down. This saves time in minor battles.
