Brook Nocturne's Links
Avalon is Brook's child.
As she cares a lot for them, she'll do anything to find them again. However, unlike her wife, Brook sometimes needs Avalon to clarify their especially cryptic, indirect comments.
Brook is the mother of Avalon.
To Avalon, she's cool, powerful, and thus, they love to play up their origin of their brand as such. Sometimes speaks a bit too cryptic around her, but tries to clarify if she's lost.
Given the general setup of the crew that Brook was assigned to work with, she...well, actually, it came to a bit of surprise to see herself tasked with watching over the others. In fact, behind that stern face was someone a bit terrified! What if someone got hurt!? The very idea terrified her, and Ferelith absolutely made all those fears a very real possibility. Still, she took the secondary job with as much gusto as she could manage, and while she wasn't keen on conversing more than she had to, she genuinely appreciated Ferelith's company.
By virtue of proximity and personality, Brook has been strong armed by the universe into the position of Ferelith's babysitter. Oblivious to the great pains Brook undertakes to keep her alive, Ferelith continues doing what she wants at any given time, but does have a lot of respect for Brook as a fellow soldier and as a friend. If Ferelith has figured out that Brook has all the social skills of a wet napkin, she sure hasn't let on, and easily carries any given interaction entirely too far in spite of Brook's usual silence through sheer force of eagerness whether Brook likes it or not.
Working under the Queen for quite some time, Brook is fairly loyal to her and, on occasion, can muster the strength to hold a decent conversation with her. Thus, when Emeline entrusts the crew with protecting her child, Rosen, Brook is eager to take the role on.
Now, years later, Brook works under Rosen, keeping an eye on them whenever the former Queen cannot. Even with Emeline's role passed on, however, Brook still speaks just as nervously -- and formally -- as she did during her time working with her. (She's doing her best to loosen up.)
Emeline is very thankful to have Brook as part of the militia, with her being devoted, loyal, and one of the more level heads of the group. When Rosen was finally revealed to the militia and then the continent at large, Emeline came to Brook occasionally for her stories of parentage, and confided in her as well. She looks forward to a rapport once she returns from her travels.
