03/30/12 - Empty Soul Gems are found during your adventuring, usually in Dwarven Cities, Warlock Dens, or Nordic Ruins. Or you can buy them (although this is horribly expensive). Fill them by using the Soul Trap Spell on a non-humanoid animal and kill it before the spell wears off. Find the spell by asking Farengar about it (in Whiterun). Or, you can use a weapon with a Soul Trap enchantment. Remember, the bigger Soul Gem, the better!
