Lankum is the brother of Sereghil and Prince of Mistal. As children, Sereghil and Lankum were close as brothers but when Lankum grew up and learnt about royalty and the throne, he was informed that Sereghil was the rightful heir to the Mistal throne, not himself. This caused Lankum to grow jealous and after repellinga bandit attack succesfully with his brother and they had finished celebrating, he struck under the dead of night. Creeping around the castle grounds late at night,he took Sereghils sword and brutally murdered a sleeping High Priest, a most horrific of crimes in Vindiscia, leaving Sereghils sword as evidence and pinning the murder on his own brother. Everybody took the bait and Sereghil was banished from Mistal.
