I almost forgot to post the results of our first roleplaying session of Cthulhu!
The Module we used (The travesty) comes from The Resurrected Vol. Two: Of Keys & Gates, of Pagan Publishing.
We were 4 players and the keeper, and although the adventure had some risky moments, the keeper was too kind (too much ;) and we all survived encounters with a cultist... and other things, I don't wan to spoil the action :)
I hope to have another session soon, it was very fun and we demostrated that statistics sometimes fall of the average and we are able to fail every spot hidden roll in a 4h play session :D
