Broken Antler Fen First Report

Sebastian explained, soothing her doubts. Of course her alpha wouldn't have sent her on a potentially dangerous mission! She couldn't think of Sebastian not a leader type though, he seemed like a wolf that was worth following. It was why she and Brandy had joined, so it was a little weird to think of the massive charcoal male NOT an alpha. His talk of tiers, however, made her wonder why his own were not filled yet. He had no mate, of course, so the lack of a female alpha was normal. But what about a BETA? Didn't all alphas pick at least one beta to help them out? 
      "Sebastian, don't alphas usually pick a beta?"
The more the tawny female thought about it, the more she thought she might want it. Why not, after all? There wasn't harm in trying for it, right? Her tone was lightly curious, and her yellow eyes were far off and suggesting that her thoughts were occupied. 

Is BAF one that accepts challenges for ranks?
