Can we please stop naming someone "False Claimant"? Aegon took Westeros by force, Robert took the throne by force. The "True Claimant" is not somebody that was born by some woman or man, it is the one that takes it by force.
You do know that others aren't raised from the dead right? There are the others (white walkers, blue eyes, extremely fast and lethal) and then there are Wights (people raised from the dead, presumably by the white walkers).
