Straff Venture is a noble man on the planet of Scadrial. He is the head of the Venture family, the most powerful great house of the the high nobility.
He is the father of Elend. He has many mistresses and sires many illegitimate children in an attempt to acquire Mistborn. He succeeds in creating Zane; in the process, because of his pure noble bloodline, he obtains quite a number of Mistings to create a considerably sized fighting force. He is also 'very fond of skaa brothels' according to Elend.
After the fall of the Lord Ruler, he proclaims himself king of the Northern Dominance. After securing this area, he lays siege to Luthadel in order to gain possession of the Lord Ruler's fabled atium cache.
He invited Elend over to his warcamp for a meeting, and the situation escalates until Straff sends his guards to kill Elend. However, Elend uses Vin to threaten Straff and manipulate Straff's emotions. Straff succumbs to his fear and lets Elend and Vin leave unharmed. After this encounter, Straff becomes terrified of Vin, commanding Zane to kill her.
One of his spurned mistress, Amaranta, poisoned him with an addictive drug, Black Frayn. Working with Zane, she caused Straff to believe that Zane is poisoning him, while Amaranta "cures" him with the addictive drug. When Zane disappeared from Straff's camp, Amaranta attempted to kill Straff with a poison. Straff realizes her betrayal, and in a fit of rage, strangles Amaranta to death. Straff nearly died but survived with a random antidote he made himself. 
Straff is German for tautly and is Swedish for penalty.
