Contract: Missing Brother
Driven by an atavistic need or some other reason beyond my comprehension, Geralt walked into an abandoned mine near the Inn at the Crossroads. Inside he found - and this surely will come as no surprise to you, dear, perceptive reader - monster tracks. He also came across a terrified woman who told him how a beast had devoured a group of men - and that the brother of one of the victims, a man named Bruno, would surely pay the witcher for slaying it.

In my experience, mines either hold precious metals or (more frequently) deadly monsters. The latter, in the form of arachasae, were present in great abundance in the Velen pits. Geralt knew he had to annihilate them for good - meaning he had to kill the female and destroy all the eggs she had lain.
Arachasae are incredibly dangerous beasts, but a witcher is not just some run-of-the-mill adventure seeker. In a bloody battle whose echoes could be heard throughout all of Velen, Geralt killed the old arachas queen and put an end to her vile line.
Though Geralt had plenty of other worries, he had not forgotten about his trade - which is, let I remind you, slaying monsters. While striving to practice his profession he came across a contract offering an altogether attractive sum in return for tracking down a certain missing individual. No mention of monsters, true, but Geralt had seen enough incidents of its like to suspect one might turn up - and besides, when it comes down to it, coin is coin...
