You have learned magic through trial and error. Gain one Spell of your choice from any Colour Lore or the Lore of Witchcraft, even if you lack the appropriate Arcane Magic Talent. Further, treat that Spell’s Channelling Skill as a Basic Skill. You can memorise an additional such Spell (and treat its Channelling Skill as Basic) for 150 XP; further Spells cost 50 XP more each time. Possession of this Talent may attract the attention of witch hunters, and complicate matters should you wish to join an established magical tradition. You can spend 100 XP to lose this Talent and all associated Spells.
