We get together after work to roll dice and pretend to be knights, assassins, wizards, heroes, and adventurers. We fight orcs and necromancers and ghosts while we explore the world, learn its secrets, and find its treasures.
Tell Colin you want to play and he'll schedule you in to one of the sessions.
You need to commit to at least one evening. One sessions is usually about 3 hours. If you like it you can keep playing.
