As one of her first acts as empress, Vaylin violently purged the entire cadre of Zakuul knights charged with protecting her brother. She replaced them with an elite unit handpicked from the remaining ranks, and called her new regiment the "Horizon Guard."
Service in the Horizon Guard is simultaneously a blessing and a curse. While it is a great honor to be chosen for the Empress's personal detail, Horizon Guards are likely to suffer the violent outbursts of Vaylin's erratic temper.
Among the other knights, it is whispered that the unofficial motto of the Horizon Guard is, "I serve for life, but I don't serve for long."
