Haven has a very indepth "introduction" quest system it basically introduces you to everything new to the AoS age through quests and tutorials. As well there are one of a kind drops there from Quests. They are blessed items and will really help you begin your journey outside of the town. It is also safe from PK's and other players until you decide it is time to go. The downside is it doesn't have dungeon skill gains and it is limiting in mobs and how far you can get. But for a player looking to learn some stuff or new to the game or even new to AoS it has those benefits. If you decide you want to leave at anytime there are two gates that let you go immediately to Britain.
