Assassin: An Isekai LitRPG Adventure

Nathan and his companions are free. For now. They're trapped inside the fortress-city of Halsmet, and every mage of Giantsrest is hunting for them. Luckily enough, they've been found by Faline, the shapeshifting leader of the Assassins of Gemore. She's pledged to teach Nathan her deadly trade. How far will he go to fight the empire of slavers? How much murder is justified? Even if they manage to win this fight against Giantsrest, it won't be the end of the conflict. A Questor from ages past lurks in the heart of the Ascendent Academy, and he won't allow Giantsrest to suffer a defeat. It is time for Nathan to face his sworn enemy, to stand against the Ascendent Academy. But how can one person fight an empire of thousands?
