Books I and II of The Quorum of Kaŝe duology by Charles Moffat. The Dragontree of Kaŝe Adaoma is working in her crystal ball and magical orb shop in the mystical hidden city of Kaŝe off the coast from Lagos, Nigeria when she receives a strange phone call from her twin sister Adaora. Her twin tells her that terrorists have escaped from Rura Penthe, the extra-dimensional prison for housing criminal wizards and witches. But to escape the clutches of the law the terrorists need a portal to another world and only one such portal exists: The Dragontree of Kaŝe. Join Adaoma and Adaora on their adventures as they travel from Nigeria and Greenland to London to Nigeria and back to the hidden city of Kaŝe as they struggle to stop the terrorists from escaping. But the terrorists didn't escape by accident. They had help from the biggest dragon anyone has ever seen. They might be skilled witches, but they are no match for a gigantic dragon that is immune to magic. The Dragonslayers of Kaŝe Adaora wants revenge on the huge ancient dragon who destroyed the mystical hidden city of Kaŝe that lies off the coast of Lagos Nigeria. Her home is in ruins and while the survivors are rebuilding the city it will never be the same. The scars run too deep. She isn't alone either. Others like her want to kill the dragon, but killing the dragon is no easy matter. It is almost completely immune to magic. Witches, war wizards, archmages... It doesn't matter. Their magic is useless against the dragon. "Like trying to kill a fish by splashing it with water." So says her twin sister Adaoma. Her twin is resistant to getting revenge on the dragon, but together Orry and Oma must find a way. They know how to get to the dragon's home world via the Dragontree of Kaŝe, and they know how to find the dragon using a new Dragonorb that Oma is making. Once they are there however they need to use some mundane means to kill the dragon - and without getting killed themselves.
