My grimoire came out and the pages went to a page where the arithmancy that Merlin and I came up with showed. One to conjure a small lightning storm. After his discovery on lightning fusing enchantments, I had quickly tested the theory myself. It led to the creation of my first sword, on top of one of the many mountains in the Scottish Highlands. Three days of waiting and I was finally able to prove his theory. Afterwards, we created this spell.
