While looking through the "Who" part of Legends and lore I found These:
When One Skrael dies He is reborn as SEVEN more Skrael so each one may go and evenge his death and SEVEN from each of those.
In the Dreams SEVEN cubed is 49.
2 Score 9 Wights is equal to 49.
Despite them being The 9 we only here of the Fates of SEVEN cleary knowing that there Avatara.
1.Alric
2.Rabican.
3.Maeldun
4.Murgen
5.Cu Roi.
6.Killed in civil War
SEVEN.Killed in Civil War
And The 6 Fallen Lords plus Balor SEVEN.
You probably know these already but If not there the ones i could figure out.
