HQ p108, "Concentrating Magic Use":
"Innate Magic: Your hero must give up all magic derived from the Otherworld: affinities, feats, charms, fetishes, spirits, scriptures, spells and grimoires, erasing them from his character sheet. He retains only his talents."
(Modified somewhat later if you 'Selfrock Teach', but certainly not including, say, Vinga affinities, which are expressly otherworldly.)
