Masters are powerful leaders in the BrikVerse, holding sway over a horde of personal minions called Thralls. The method of control and the type of these creatures is left entirely to the Player's imagination. The identifying aspect of the relationship is the Master's ability to Sacrifice those under his command for some temporary benefit. Masters tend to be dynamic characters. While most come pre-equipped with natural Thralls, some Masters (such as the SuperNatural variety) have the ability to create more Thralls or convert enemy minifigs into Thralls.
