Ira

The 5th layer of the seven hells, the layer of wrath. Ira is surprisingly easy to access from Acedia, numerous pathway leading from one layer to another without any real restriction as Aaron love to be visited by creature only to slay them. The layer look like a constant battlefield, lacking soldiers, only the skeleton of those slain By Aaron dot the ground, their sword still standing, anchored in the ground. The land is swept by powerful frozen winds that freeze those who hide and lower the chance of ranged attacks.

Geography

Blade Forest

The majority of the layer is covered by the blade forest, the remains of a giant battlefield, the sword of those who were fighting standing next to their skeleton. In the middle of this forest, Aaron palace stand tall, his throne made of thousands of sword towering above the forest.

Metals glades

However, amidst this brutal forest, there exists a contrasting feature—an endless expanse of treacherous swampland. This never-ending swamp serves as an eternal battleground, where the fallen blades gradually sink into the mire, contributing to the ongoing transformation of the swamp into the blade forest.

Features

Pressured Outburst. The archdevil of wrath's sin creates a potent aura that instills others to unleash their own rage. When a creature enters this plane, they must make a DC 12 Wisdom saving throw. On a failure, they begin to rage. While raging the creature has advantage on Strength checks and saving throws, has resistance to bludgeoning, piercing, and slashing damage, and can neither cast nor concentrate on spells. This effect can be ended via the Greater Restoration spell.

Hazard

Ira's Curse. Whenever a creature damages you, you must succeed on a DC 10 Wisdom saving throw or you must use your reaction to move up to your movement speed and attack the creature nearest to you. If you have multiple possible targets, you attack one at random.
Frozen wind. A force with an almost malevolent intelligence that chases down creatures through iceberg canyons and across blasted stretches of barren tundra. It is widely believed the frozen winds of Ira are a direct manifestation of Aaron.
When a frozen wind strikes, two effects take place. The first is the area is under the effects of strong wind. A strong wind imposes disadvantage on ranged weapon attack rolls and Wisdom (Perception) checks that rely on hearing. A strong wind also extinguishes open flames, disperses fog, and makes flying by nonmagical means nearly impossible. A flying creature in a strong wind must land at the end of its turn or fall. The second is biting cold, and creatures within the area must make a DC 15 Constitution saving throw, suffering 18 (4d8) cold damage on a failure, or half as much on a success. The saving throw must be repeated every minute a creature remains in the frozen wind. Bouts of frozen wind typically last 2d12 minutes.

Ruler

Aaron is the ruler of Ira. His throne in the Blade forest allows him to catch over the whole layer.
