Silvos is Leader, and there are a fair few sackholders around.
Sign up on the forum and request a pearl, you will be welcomed.
There are a good number of members and the shell is semi casual/social, you just need to be committed to levelling BST or SMN and want to hang out with similar players.
We do some events, we did an all BST Promy Mea a few weeks ago succesfully, we are organising a Holla soon.
Lots of us have been teaming up to collect AF pieces, do limit breaks etc.
Some of the higher level members are discussing organising O-Hat runs.
