For a time Glasya was a capricious schemer dating back to the Reckoning, and continuing more recently into currency fraud involving souls within the Nine Hells. It was Asmodeus himself who put a hold on Glasya's plans by elevating her to Archdevil, and jailer of Malbolge. With this duty Asmodeus confined her to only entice souls through delving into matters of contracts, bargains, and legalities. 

Despite her new responsibility as a jailer she may adorn herself in luxurious jewels, clothes, and finery worth several thousands of gold. Glasya appears as a 9 foot tall, black-haired figure with leathery wings similar in form to a succubus. Her skin has a copper tone, however it is more metallic when compared to normal humanoids. Even if her duties may keep her busy from indulging in favorite pastimes she can experience them vicariously through any favored fiend tempting mortals, such as an erinyes or succubus.

The desire to acquire more souls never stopped, as it shouldn't for any devil. Glasya and her agents offer mortals advice on how to manipulate, or identify loop holes and escape clauses within the law. Whatever it is mortals desire Glasya will help them obtain it without violating legal precedent. Petitioners may want power, money, and love...with some wanting out of dark bargains with another devil. This scrupulous nature has earned her ire from stronger Archdevils, but solidified her place on Malbolge.

glasya's keen scourge of speed. While wielding this weapon Glasya is able to use the Scourge presented under her actions, and ignores all other properties in this weapon's description.

Weapon (whip), legendary (requires attunement)
While Glasya was known to wield a short sword that had speed and was virulent, she later replaced it with this scourge. Her scourge shares the same speed of her older weapon, but has been made exceptionally sharp as opposed to poisoned. Any humanoid killed by an attack made with this weapon has its soul funneled into the River Styx, deposited into the Birthing Pools of Malbolge where it reemerges as a lemure devil after the agonizing experience.

You have a +3 bonus to attack and damage rolls made with this magic weapon. When you hit a creature with it, that creature takes an extra 1d4 slashing damage. In addition, you can make one attack with it as a bonus action on each of your turns, and any attacks made with this weapon score a critical hit on a roll of 19 or 20.

Proficiency with a whip allows you to add your proficiency bonus to the attack roll for any attack you make with it.

Glasya’s Lair

Glasya's lair is Osseia with the palace being made from the skull of the previous Hag Countess, Malagard. Ten towers circle around Osseia made from the finger bones of the hag; one was made the Tower of Pain for torturing Glasya's most dangerous enemies, while the other towers became guard posts. The citadel is situated atop adamantine pillars that appear to teeter on the edge of collapse, and yet remain sturdy. Malbolge acts as a prison for those found guilty in the courts of Phlegethos, and the condemned hang trapped in dangling cages beneath supported platforms. Centered within Osseia, the Garden of Delights, is rumored to be a small refuge of hope. Conversely the Hair Forest, or Forest of Sighs, is Glasya's dumping ground for lemure and other hideous monstrosities. The body of Malagard has mostly rotted away, and the return of older Malbolge pokes out as obsidian crags crumbling into deafening avalanches. Some have taken to the caves, and tunnels in the infinite slope for shelter, but Malbolge remains a twisted place of extremes reflecting its ruler.

Lair Actions

On initiative count 20 (losing initiative ties), Glasya can take one of the following lair actions; she can't take the same lair action two rounds in a row:

Promises from the Garden of Delights.  Glasya's words invoke images of pleasure. Each creature that can hear Glasya within 120 feet must make a DC 20 Wisdom saving throw, or become magically charmed until the start of its turn. Charmed creatures must immediately use their reaction, if available, to move as close as its speed allows towards Glasya. Creatures don't move into obviously dangerous ground, such as a fire or a pit.

Cries from the Forest of Sighs. Glasya's words invoke images of torment. Each creatures that can hear Glasya within 120 feet must make a DC 20 Wisdom saving throw, or become magically frightened until the start of its turn. Frightened creatures must immediately use their reaction, if available, to move as far as its speed allows away from Glasya. Creatures don't move into obviously dangerous ground, such as a fire or a pit.

Regional Effects

The region containing Glasya's lair is warped by magic, which creates one or more of the following effects:

Osseia. The general area of the lair is filled with muffled screams beneath rotten soil, and sounds of distant tumultuous avalanches. Closer towards the palace music plays with an ominous mood. Humanoids only regain hit points from one hit dice when finishing a short rest, or long rest within Osseia.

Garden of Delights. While humanoids are inside the gardens they ignore the regional effects of Osseia, and are imposed with disadvantage on saving throws against being charmed.

Forest of Sighs. Falling damage is doubled on trees, and counts as piercing. Creatures impaled on trees don't die, and are stabilized by tiny roots growing from the tree. The creature becomes stable for 10 years after which it dies with the soul consumed forever requiring a wish spell to be restored.

If Glasya dies, these effects fade over the course of 1d10 days, and return in the same amount of time after she returns.

Cultists of Glasya

Glasya grants special abilities to her most loyal cultists. They can gain the Step into Shadows trait, and her cult’s leaders can also gain the Infernal Ring Leader trait.

Step into Shadows (Recharges after a Short or Long Rest). As an action, this creature, along with anything it is wearing and carrying, magically becomes invisible until the end of its next turn.

Infernal Ring Leader. As a reaction when this creature is hit by an attack, it can choose one ally it can see within 5 feet of it and cause that ally to be hit by that attack instead.
