The simplest way to visualize Hell is a square at a 45 degree angle. In the center is a medium sized city known as Sind, where those who have repented wait for final judgement, or those banned from paradise reside. The center of the city houses the Palace of Grimora, Goddess of Darkness and Queen of the Damned.
The surrounding area is split into four areas, which themselves are split into four sections, for a total of 16 separate locations in Hell (17 if you include the city). The sections are equal in size, with some deeper but thinner and others wider but shorter. There is a slight decline as you travel away from the city. The farther the section is from the city of Sind, the worse the Sin in the eyes of the gods, and one must start at the deepest level of their sins and work their way up towards the city. Once one has sufficiently repented, one moves to the next area where they repent if they must for that sin. Once they finish an area, they are sent to another area if need be, until they have given proper penance for their sins and wait in Sind to either ascend or reincarnate (depending on the situation).
To the north of Sind, souls pay penance for the Sin of Violence. First, those violent to others stand in a sea of boiling blood. How deep they are depends on how violent they were in life. Second is for those violent towards children and animals, who are tortured relentlessly by demonic animals and children. The third section is for those violent against themselves. They must flee from wolves trying to eat them alive while wounds constantly appear on their bodies. Finally, the deepest section is for those violent against nature and the gods themselves. These souls wonder a scorching desert naked with a sun burning above, devoid of anything and anyone but the other sinners, suffering in the intense heat.
To the south of Sind is for the Covetous. First, the Lecherous, those that sinfully sought physical pleasure and lustfulness, leap through great pillars of flames representing the fire in their loins. Second, the Greedy, those who focused solely on material gain to a sinful degree, are scorched by and force fed molten gold. Third, the Conspicuous, those the sought fame and renown regardless of who it harmed, wonder alone through the tattered remains of a ghost town, wind and rain lashing at them. Finally, the Ambitious, those willing to step on others to seek power and influence, lay helpless as demons exert their power over the sinners in a variety of ways.
To the east of Sind lies the land of the Treacherous. First, betrayers of family are hung on sharp, iron trees. Second, betrayers of friends and those whom one has earned trust with are sawed in half by demons. Third betrayers on a city or country size scale must themselves scale a mountain of knives. Finally, those who have betrayed the gods themselves wonder naked in a river of freezing water.
Finally, the west part of Hell is for the Proud. First, the arrogant who looked down on others and put themselves above the world carry a gigantic boulder representing the weight of the world on their back. Second, the gluttonous, those whose pride led them to take more food then was deserved, sit starving in a lake of bile and saliva while the must succulent food dangles just beyond reach. Third, the Slothful, those whose pride led the to laziness, expecting others to do their work for them, are forced to constantly run from a flock of demonic birds, never able to slow down less the birds catch them and rip them apart. Finally, the envious, those whose pride made them look with grudging hatred upon other men's gifts and good fortune, taking every opportunity to run them down or deprive them of their happiness, wonder a forest of thorns with their eyes sown shut with metal wire.
