I'll remember the names of a select few of my more special... "friends". However, it's dangerous to keep it floating around openly. Just as easily as I can take it, other faeries can take it, too, or their friends or family can take and give it back to them. Thus, I've got two options if I plan on keeping said "friend" around for longer than a day or so.

1.) I can just get "rid" of it completely and make them nameless. This is the best option if I only wanna mess around with someone for a week or so before eating them. Nobody can take or take back their name if they don't even have one anymore. :3 However, I do lose some of my control over them if I do that. (I've got other ways to gain control over them though, via gifts, giving them something to eat or drink in my realm, etc.)

2.) I can go a little farther than #1 and give them a NEW name that only I know of. :3 This is the default option for those who can do something special for me -- for example, if someone has a pretty voice or can play and instrument, it's not uncommon for me to keep them for longer than a week just to sing or play for me. <3 I don't lose ANY control over them in this case. In fact, my "gift" to them gives me even more power over them. >:3 Of course, once I've become bored with them or they've grown useless, I simply take back the name and expend them to fill out my shape, like all the others. <3
