An E'roni tower guard served in the U'ronoh village, a mining settlement, throughout the High Republic Era. This guard met their death in 382 BBY at the hands of the Children of E'ronoh, a group of dissidents, while on duty at the village's mining tower. Subsequent to eliminating the guard, the dissidents readied themselves for an attack against U'ronoh, an attempt that was ultimately prevented by the intervention of Jedi Knight Gella Nattai and Republic envoy Axel Greylark. Later, a Remembrance was conducted for both the tower guard and a Tintinna man at the Siggi's tavern establishment, where tales were shared concerning the two individuals who perished that day.
Zoraida Córdova mentioned the tower guard in her 2022 novel, Convergence. This novel is a component of Phase II of the Star Wars: The High Republic multimedia project.
