There are a decent number of endgame shells on Figaro. Each has slightly different attitudes and styles. Most shells have a typical "hang out" spot on the Ul'dahn strip, so you shouldn't have trouble finding someone. Ultimately, I suggest simply getting to know people - you'll get an invite or two before long.

On the other side of the coin, I'm keen on joining your shell, since I'm east coat Australian. After the merge, send me a tell. I'm usually on weekends from the morning onwards (but won't be over the Easter Holidays).
