There could have been multiple undead that have linked the fire. Hell, if you kept Solaire alive for the whole game, so that you could summon him for the fight against Gwyn, it is highly implied that he would have opted to link the flame; to create his own sun. The timeline we are in could very well be Solaire's!! That would be neat.
