First ye must begin your journey by traveling several days south to the hell pits. After stopping for a quick bite to eat at the local Denny's, you'll make your way towards the great Cragtooth Mountains. Their you'll must likely be set upon by the arachnid-women indigenous to the region. Do not be tempted! Each of them be virgins and each one's hymen is a gateway to the farthest corners of the black void of Ulzricor the unknowing, a land from which your penis shall never escape.
Assuming you've braved the challenges so far, you'll make your way to Blackthorn Pass, the lair of the Minotaur Tribe. They'll only allow you safe passage if you can best their greatest champion in a wood wind instrument competition (fear their mighty piccolo skill). Having crossed their land you'll find yourself on the coast of The Sea of Sehaman. You'll find several large pieces of driftwood along the shoreline from which you can produce a raft. Make sure your craft is sturdy for those who fall into those (very) salty depths are never heard from again.
Finally, you'll enter the Dwarven Hold of Khar'Dash'Makar on the other side of those rough waters. Find a shop called "The Kobold's Tail". Tell the shopkeep Bill sent you and you'll find your precious monstergirl hentai.
