If you settle in at the Garden Gallery, you will gain a 2 point Bonus to Social Actions and a 1 point Increase to your Gossip skill for the duration of your stay.
Nestled in a leafy nook at Campus Avila, the Garden Gallery is a quiet, relaxing place to gossip and hang out. The stone benches of the garden are particularly famous, most of htem carved into the strange shapes of mythical and real monsters. Also, you can find some fairly dangerous plants if you stray too far from the various paths.
That said, there are fewer better places to start and spread a rumor, as there are almost always a couple of Students here, ready to talk about the day's events.
