Hmm, i can relate to this as graal can be a lonely game. I mean come on none of my friends even play graal in real life and friends you make in graal you will most likely never meet at all.
As for you being shy i can tell you that being on graalians will be the best thing for you. Why? Well you can get "internet friends" that you can then speak too. And i guess you may just have to engage more at somepoint
