so im a little confused about this cuz they have like 10 people with the same name but is the aemon on the wall aemon the dragon knight or was that before him? and why did he go to the wall in the first place?
Aemon is named after the dragon knight. He went to the Night's Watch because he was afraid that people might try to overthrow his brother, using him as an excuse. But, if he joined the watch, he would have to give up all claims, thus keeping his brother, Aegon V safe.
