Destiny Guide to The Tower
The Tower is one of the most important locations in Destiny. It serves as a base of operations and it is the place worth coming back to after each long journey. The Tower is considered a safe sanctuary, so you do not have to worry about encountering enemies or hostile players here. Instead, a lot of activities await you here, the most important of which being:
1)Making purchases from merchants - Their offer is very diverse. E.g. you can buy new weapons, armor, emblems, or spaceships.
2)Taking new missions - This refers to both main missions as well as minor jobs received from factions.
3)Storing items that you have no use of at the moment - You can put them in the Vault.
4)Receiving messages - You receive them from Postmaster.
5)Meeting other players - You can check their progress, invite them to your Fireteam or add to your friends list.
If you have troubles with finding your way around the Tower, talk to one of the drones residing there. This will display a map with your position and the important NPC's marked on it.
