House Deathwatch consists of a group of elite members from Clan Vizsla. Originally a Mandalorian splinter group that was anti pacifist originally founded by Tor Vizsla and led by Pre Vizsla before and during the Clone Wars. The original purpose of the Deathwatch was to retake Mandalore both to govern and reinstate their warrior culture. However, they did not succeed and were eventually disbanded.

In 37 ABY Appius Wight took inspiration from the group of the past and created a brand new Battleteam with a new purpose: to protect House Wren's assets and be the tip of the spear. To conduct secret missions into and above the underworld to eliminate targets and destroy unwelcome trades such as slavery, drugs, child labor and human trafficking. He thus named this new Battleteam "Deathwatch."

Deathwatch was elevated to full House Status by Consul Dracaryis and is Clan Vizsla’s second official house.
