Iolo* joins you at the beginning of the game. Spark* -- soon after (he is from Trinsic). He is not so good at the beginning, but he trains quickly and efficiently. Shamino* -- in Britain. (Try to ask him about that girl...) Sentry -- in Britain. If he joins you, he'll train you for free. Dupre* -- in Jhelom. He is very strong. Tseramed -- in Yew. He is a good archer and brings you some very useful sleep arrows. He also directs you through the bee cave. Janna, Catherina and others -- are not really necessary.
