Talk:Merlin

Hogwarts Attendance
I do realise that his house was revealed on Pottermore, but since the legend of King Arthur was said to be in roughly the 600's AD, wouldn't this make it impossible for Merlin to have attended the school which was founded in the late 10th century? And the list of English Kings goes back to late 700's with a good deal of certainty, meaning Arthur would have had to have come before. Could this be a Slytherin attempt to make their house look good?
