Star Trek: Edge of Apocalypse
An advanced world that still favours more rural lifestyles, Tammeron has a reputation as a major agricultural center, and is famous for its Tammeron grain. The spread of replicator technology has not been a boon to Tammeron. It also serves as a central communications relay in the sector, which is of use to the many Starfleet starbases around the edges of this space. Traffic through the system is usually only a small number of civilian freighters.
Early during the Dominion War, a squad of Jem’Hadar infiltrators were snuck through Starfleet’s defences and onto the planet, where they began conducting guerilla raids and sabotage, mostly focused on the communications relay tower. While the rest of the 8th Fleet supported Operation Return, the Agora was diverted to Tammeron to deal with these intruders. They were eventually tracked down to their mountain cave hideout, which the Agora’s crew opted to wipe out entirely with the ship’s phasers, leaving a massive lava pool in the mountain.
