Baernaloth

Creature
Baernoloths are one of the biggest mysteries of the multiverse. They wander in solitude, they scheme and discard them for something even more terrible. According to the rumors, they created the yugoloths and demodands. Whether it's true or not, they are powerful. Even the yugoloths give them a wide berth.

A baernaloth is a tall, lanky creature, with long limbs. Its head is huge with large curving horns, and its mouth looks like that of a skeletal horse, with skin stretched over it. Its gray skin drips with pus, and its faraway, glassy yellow eyes ooze a revolting liquid. Though they travel alone most of the time, they occasionally take night hags or nightmares for companions.

They stand about 8 feet tall and weighs 500 pounds.

Combat
The baernoloths are canny, unfathomable creatures. Their plans, schemes and agendas span the ages of the multiverse. The plans of a particular baern can come to fruition next week or 1000 years later.

They are equally capable combatants tough they often toy with their opponents before transforming them into some humiliating form with their deform ability. They can mutate and control their enemies with  spell.

They possess powerful spellcasting or psionic abilities.

Habitat
Almost nothing is known from their schemes, and they are encountered in different forms all over the multiverse. Gehenna and Gray Waste are their favorite places.
