Well, recently a member of the wiki edited the page Ahzidal, writing in the "Trivia" section that he may had enchanted Wuuthrad and the Shield of Ysgramor himself. This change was removed under the reason of "especulation", but considering the great apptitude Ahzidal had for magic, his hatred for elves and analysing the time line of the Merethic Era, what is your opinion on the subject?
