From Destinypedia, the Destiny wiki
The Tower was a location in the Last City, located along the outer wall. It was the headquarters of the Vanguard, home of the Speaker, and where Guardians returned to report and rest between missions. Guardians could visit vendors, turn in quests, and interact with their fellows in the stronghold.
According to Tyra Karn, at the height of the Last City's militarization and centralization, it was defended by eight total towers manned by Titans. Aside from the Tower and Bannerfall, the others had been repurposed over centuries of conflict.
The Tower was the first target attacked by the Cabal Red Legion during their invasion of the Last City, one year after the SIVA Crisis. Guardians stalled the Red Legion troops while civilians were evacuated, but the Speaker went missing. The Tower was subsequently destroyed, and the Guardians were forced to relocate to The Farm.
Following the defeat of Ghaul and liberation of the Last City, the Guardians relocate to a new base on the wall beneath the ruins of the old Tower.
In Destiny, The Tower acts as the main hub for Guardians in between missions or Crucible matches. It is one of four "Social Spaces" available in the game, the others being the Vestian Outpost in the Reef (available in House of Wolves); the Lighthouse, available after going flawless in Trials of Osiris, and the Iron Temple on Felwinter Peak (available in Rise of Iron). At the Tower, Guardians can interact with fellow Guardians, or the many NPCs present.
