This symbol functioned as the personal emblem for Admiral Trench.
Trench was known for using this emblem to designate his personal command ships. The presence of this symbol on the Separatist dreadnaught named Invincible gave away Admiral Wullf Yularen's opponent's identity to the Republic officer during the Battle of Christophsis in 22 BBY, as he had previously encountered it during the Battle of Malastare Narrows.
