Tanith Low is a Hidden Blade magic user skilled in combat, stealth, walking on walls (and sitting on ceilings), and swordsmanship. She's an ally of Skulduggery Pleasant and the honorary big sister of Pleasant's apprentice, Valkyrie Cain. It is, in fact, Tanith, who first inspired Valkyrie to pick her name after casually using the phrase "raising Cain" (making trouble).
