Solara

Solara. Known for her fiery temper and exceptionally keen eyesight, Solara is an Enclave infiltration specialist who became a Dashite through an unexpected turn of events. Ex-marefriend to Second Lieutenant Mach, also a Dashite, Solara goes AWOL in order to reunite with him, fleeing the sanctuary of the cloud cover once the Enclave starts making preparations to move forward with Operation: Cauterize.

Only... Solara is acting different from Mach's memory of her. What could have changed in the few weeks they were apart from each other? Could she be hiding something? All will be revealed in time, but only by reading my sidefic, Fallout Equestria: Outlaw, right here: [link]

Yes, that is a balefire egg in her hoof.
