There are several classes of power within the guild, from meagre Thieves and Assassins to the more powerful Dark Assassins, and then the Strikers. The title of Striker is reserved for the highest class of assassins, and the leader of the guild is usually a Striker.
There are five known members of the Guild.
Lass is a mysterious, shady young boy who was possessed by Kaze'aze. He is then freed from her grasp thanks to the Grand Chase, and vows to "start fresh". However, his past seems to be mixed up and yet he refuses to talk about it. As he journeys farther, the Knight Master compliments on his actions, but then requests he slays monsters upon Bermesiahn lands. At some point, he becomes the guild's leader. He, like every other Assassin, is a quick and agile opponent, who relies on quick slashes and powerful blows to deal upon a foe.
The other known member is the official guild leader that is only mentioned in quest dialogue of Striker. He, like Magnus Dan, led the Assassins and trained them under his might until he grew too old to fight and chose Lass to be his successor. After the events of Battle for Bermesiah, Lass inherited his position as well as his nodachi, along with the skill of drawing the blade from its scabbard at lightning speed.
There are also three female characters in the guild, Dina, Mona, and Sena. The trio serves as Lass's bodyguards and escort him secretly from the shadows, protecting him from danger. However, their concept arts and information on Naver blog seems to portray them as cheerleaders and fangirls rather than bodyguards.
- The Elsword Guild Night Savers are based off of the Silver Cross Thieves.
- Despite the official name "Silver Cross Thieves", the guild seems focus more on assassinations rather than thievery.
- Despite that thievery and assassination are generally viewed as negative, the Dark Assassin description points out that the Silver Cross Thieves fight against evil and have allied with the Elven Corps and the Violet Mages.
- It is ironic that the guild is led by a child, as most others would not follow the commands of someone younger.
- According to the Naver Blog, the Strikers called their entire force the "Guild of the Strikers", despite that there are others.
