The Sword of Gryffindor in Harry Potter only absorbs what makes it stronger. So, what would happen if I swung a Star Wars lightsaber at it?
Just imagine for a moment a wonderful theoretical universe, where Neville Longbottom could share a butterbeer in the Star Wars Cantina with Han Solo. Are you there yet? Good, then we’ll begin.
Harry Potter’s thousand-year-old Sword of Gryffindor was fashioned from pure silver by Ragnuk the First, finest of goblin silversmiths. Goblin silver is unique, in that it only pulls in what makes it stronger.
Which is how it absorbed the basilisk’s venom in Harry Potter and the Chamber of Secrets… which is how it managed to do away with all those pesky Horcruxes. Convenient, eh?
Anyway, here’s the (Tom) Riddle. A Star Wars lightsaber is not a ‘blade’ in the conventional sense at all, but a pure beam of energy focused by a series of lightsaber crystals.
So, what would happen if, say, Harry Potter and Darth Vader were to cross swords? Would the Sword of Gryffindor absorb the lightsaber’s shimmering force? Could a Sith cut through goblin silver? Or would the two simply pass through each other in a puff of ficto-physical impossibility?
The quizzical folks over at Ask Science Fiction first posed this question. and it’s been in-Vader-ing our brains ever since.
