In the Windemere Wood area of Tartarus, on a small point of land north of Sacrifice Shrine is a ruined old castle which rests in darkness. It was built over a sealed crevice that leads to a realm of mighty creatures and untold danger. This castle is what is left of the home of a mighty faction . . the 'Ordo Venatori'.
The Ordo Venatori (Order of Hunters) was a powerful group of mighty hunters. Their numbers included such legends as Woden, Cernunnos, Nodens, Arawn, Dagda and Yhaguen to mention a few. Today . . few remain. Most have been slain and the Ordo Venatori is but a shadow of its former glory. Nonetheless . . what remains is formidable. They look to rebuild and seek those who would test themselves in the realm below.
If you have honed your (Warrior, Tamer or Sorcerer) skills and are up to the Ordo Venatori challenge then you could venture to their castle and talk to the Princeps (leader) of the Ordo Venatori.
He can help you open the crevice and if you succeed below he will reward your effort. Should you accept this adventure you will face a 24 hour cool down period before he will offer you another.
*We can thank Yhaguen for this concept and for funding (in-game gold) its construction*
