Johan grew up in Port Blacksand. He’s respected in the highly successful Thieves’ Guild there as an ‘entry specialist’, with a sharp mind and even sharper eyes. He commands a decent price, but is also known as reliable and relatively fair-minded, a rare commodity indeed amongst the humanoid scum of that brawling city.
He has recently been recruited by no less a personage than the wizard Nicodemus to retrieve an artifact known as the Amulet of Yeldoon from Undermountain. He has no idea what the item is, or why the wizard wants it, but is frankly relieved to be out of Blacksand for a while anyway, and is making the most of the business trip to make a name for himself elsewhere. He’s particularly amused to have been subcontracted to the temple of Heironius, a band of stiff-backed templars who would ordinarily have nothing to do with a master of skulduggery like himself.
He is backed up in terms of muscle by the almost sentient half-orc, Ug Ortha, a mercenary he’s worked with for many years.
