Lian North successfully formed a team with Aria and Thorn, pooling their resources to challenge higher-level floor bosses.
Naturally, the trio ensured they took appropriate breaks to replenish their resources, making optimal use of the buffer time provided by the Shaynak Tower to train and strategize.
Eren refrained from taking over Lian's body for the most part, instead conveying his ideas and allowing Lian to execute them to the best of his abilities.
Eren understood that direct control of his pseudo-avatars wasn't always the best choice, sometimes requiring trust in their abilities.
With Lian's competence as a Summoner and strategist, Eren had little cause for concern regarding the management of matters related to the Shaynak tower.
Predictably, Lian North emerged as the top earner of Origin Force Points among all of Eren's pseudo-avatars.
