Harry Potterish

Thought I'd try and have some fun with Riddle and noticed that 'ràdh dorcha' can mean a riddle, obviously not a translation that fits exactly with what the author might want but it sounds a bit Harry Potterish - could we have Taigh nan Riddles?Taigh an tòimhseachan?An Teaghlach MhicTòimhseach?That's without looking at the other function of the word riddle.
