Eichkonigs are towering treants that are corrupted by dark magic. They may originally have been trees awoken by necromancers or crazed druids, or treants that succumbed to the greater, wide-scale destruction of an entire forest. Their root systems spread deep beneath the ground, slowly infecting the surrounding earth with their malevolent intent. They creep into burrows, strangling the animals inside, consuming their essence as sustenance and raising them again as mindless undead servants. 

While a treant may be a wise and ancient being with a duty to protect the forest, eichkonigs are perverted reflections of their former selves. They retain only a dim conscious awareness and are propelled by a vague instinct to spread their hivemind of undeath as far as they can muster. Each creature that succumbs to the twisting, rotting roots of the eichkonig becomes an extension of the eichkonigs mind, through which the tree can sense and communicate. 

An eichkonig gradually kills all other trees and life within its realm of influence. This results in increased termite populations, though the termites that feed on eichkonigs and the dead wood that surrounds them begin to emanate a soft purple glow as a result of necromantic absorption. The presence of these glowing termites is one the first and obvious signs of a nearby eichkonig. Trees and other plants killed by an eichkonig begin to twist into unnatural spiralling patterns. 

Water blessed by sun deity or one of its priests cleanses and restores the land afflicted by an eichkonig. An ingested solution of one part sheep’s blood mixed with one part salt provides resistance against the eichkonig’s necrotic energies. Edged weapons touched by the tears of fairies cut through its wood like butter. 

The forest becomes increasingly blackened and necrotic in proximity to an eichkonig. Within a half-mile radius of the eichkonig, the wood of dead trees and rotting biomass is woven together to form spiralling mazes that block out all light. These mazes are patrolled by zombified forest dwellers; extensions of the eichkonig hivemind. 

The eichkonig is usually aided by at least two other creatures that it has raised using its Reanimate ability. It uses its Entangling Roots ability as soon as it is able, and as often as it recharges. It prioritises enemies with lower Strength scores, if possible. If the party has a capable melee attacker in the group, the eichkonig uses its first legendary actions on its Enfeebling Root ability in an attempt to mitigate their damage. It otherwise uses its legendary actions on its Command Corpse ability, if applicable, followed by its Attack and Throw. 

The bark from an eichkonig’s trunk is believed to be able to bring the recently deceased back to life. Its roots, when mixed with powdered silver into an ingestible powder, allow one to summon demons.  A PC can make a 

 Wisdom (Survival) check, or other check the GM deems appropriate, to obtain loot from  the swordbearer. On a successful check, the GM chooses one piece of loot, or has the PC roll a d4 to determine what they get. On a failed check, the PC gets 1d6 pieces of eichkonig's bark. A PC can choose to have another make their skill check if they so choose.

When you place this piece bark upon your chest, you can use an action to speak its command word and cast the 

 spell on yourself. When you cast the spell using this bark, you do not need to concentrate on it. The bark dries up and cracks when the spell ends.

When you apply this sap to a wound on a creature that died within the last minute, that creature returns to life with 1 hit point. This sap can't return to life a creature that has died of old age, nor can it restore any missing body parts.

You can mix this root with powdered silver by making a 

 Wisdom or Intelligence check using Alchemist Supplies. On a failed save, a random fiend that has a challenge rating between 0 and 5 appears in a space adjacent to you and is not in the best of moods. On a successful check you create a potion of demon summoning.  As an action you can throw this potion up to 40 feet into an unoccupied space, summoning a random fiend that has a challenge rating between 2 and 7. A summoned demon does as it pleases, can't summon other demons, and remains for 1 minute.

A creature that spends 8 hours carving this branch into a staff must make a 

 Dexterity, Intelligence, or Wisdom check using Woodcarver's Tools. On a successful check, the staff becomes a Staff of Swarming Insects. On a failed save, it becomes a normal quarterstaff.
