Tachros

A deserter of Mediahn conflicts, Tachros would join the rebels of Cron Castle and became the right-hand man of their first captain.
Yet, not long after, Giath, king of the Goblins, launched a full-scale assault on Cron Castle, which lead to death of countless rebels, including Tachros' former captain. Finding no reason to continue fighting, he departed for Velia, where he remains instructing trainee soldiers.

Many adventurers visit Velia to see Tachros and learn from his deep knowledge of battle techniques.
