Sela was a female mouse and a member of the Mouse Guard. Her chosen weapon was a sword.

During the 1152's winter, Sela - alongside her fellow Guardmice Elymis, Annika and Cerise - was sent to the mouse settlements of Darkwater, Lonepine, Burl, Sandmason and Mapleharbour to gather supplies for Lockhaven's larders.[1]

The group arrived back towards the end of winter, after successfully securing supplies for the Guard. The following spring, Cerise and Sela were once again sent to gather food, which they completed with the help of some common mice.[2]
