When I was reading the Wanderer's Guidebook today (I was bored and going through old documents), it lists Lyn and Blood Lyn as separate groups.
I never thought of this, I always thought Lyn and Blood Lyn were the same. They just had various names. Was it ever confirmed in the games that Lyn and Blood Lyn are two separate groups?

"Lyn" is just a general term for a warrior, or someone who takes the plunge.

"Blood Lyn" is a strict faction of lyn lead by the Blana Sera.
