Welte Talan functions as a critical aide to exiled leader Abelt Desler after the Garmillas Empire's downfall. Operating within Desler's remnant faction, he maintains communications with rogue military forces still loyal to the former ruler, including Major General Gremdt Goer's resisting fleet.

Talan receives a transmission where Goer boasts of commanding the loyalist fleet. Displaying impatience, Talan terminates the report abruptly and directly questions Desler about their continued pursuit of the Yamato, highlighting his strategic coordination role.

He is the brother of Ghader Talan, the newly appointed minister in Admiral Ditz's reformed Garmillas government. Ghader voices concern over Welte's disappearance during the Battle of Garmillas, with no updates on his status increasing the likelihood he perished there.

Following Goer's death, remnants of his fleet potentially rally under Talan and Desler's command, though Talan's ultimate fate remains unresolved since his disappearance.
