Skirmish near Threllvia IV

The Battle of Threllvia IV was a battle between the Romulan Star Empire and the Andorian Empire over the Andorian colony of Threllvia IV.

Background
Due to the Vulcan decision to withdraw from the war, Andorian forces were spread thin in an effort to defend Andorian possessions as well as those of the Coalition allies, leaving defenses at the far flung colony of world Threllvia IV undefended. 

The Battle
As the Andorian Imperial Guard vessel Ka'Thelan Krotus was on guard in over Threllvia when three Romulan Birds-of-Prey attacked her. During the attack the Romulans tried to take over the Ka'Thelan Krotus with their telecapture system, but the Andorian vessel self-destructed to prevent her capture. 

Aftermath
The Romulan captured Threllvia, giving them yet another foothold in Coalition territory and cause former Imperial Guard officer Shran to rejoin the Guard in order to help to defend his world and avenge those that he knew aboard the Ka'Thelan Krotus.
