Braer was also a devote worshiper of Mystra, a choice unusual for a elf. Was Mystra herself in her mortal disguise that asked to Braer to tutor in magic art the young Elminster and so Braer become the fist magic teacher of El. After Elminster learned all he can the two partnered ways. Years later Elminster, by now a powerful wizard, come to ask the help of Braer and his fellow elves in his insurrection against the Magelords of Athalantar; Braer agreed and was decisive in the battle but in the end Braer transformed in a Silver dragon and confronted the Black dragon of magelord Undarl but in the fighting died both of them.
