Barrier Against Darkness

From publisher blurb: O forte que protege uma das fronteiras do reino está sob constante ataque de criaturas oriundas das trevas. Aventureiros são chamados para tentar acabar com este sofrimento, será que conseguirão? The military fort that protects one of the kingdom's borders is facing dark creatures for almost a year. They try to invade the kingdom under the command of one person who calls himself Emperor, an ancient wizard who is rumored to have made a pact with darkness and obtained the power to command dark armies. As members of the kingdom's armed forces are dedicated to containing its advances, assassins and people of courage are hired to eliminate the Emperor, and thus stop such terror.
