Suvudu’s running another cage match (after their previous, massively-popular one in which Jaime Lannister narrowly lost to Rand al’Thor), and this time the representative for A Song of Ice and Fire is none other than Ser Gregor Clegane, the Mountain that Rides. He’s been pitted against Dracula, and could use your support to put an end to the undead vampire count.
Really, I think old Vlad would turn tail and flap his bat wings away if he came face to face with this monstroous knight.
