Lion's Arch is one of the most popular locations in Guild Wars. In fact, the ArenaNet team likes it enough to use it for the occasional chit-chat with the community. Don't believe me? Wait till the frog talks.
This prime real estate is owned by the White Mantle. Stormy skies and wheeling seagulls help make this town one of the most visually interesting in the game.
