Mythos undead resemble generic undead in many ways—mindless or fully intelligent, weak or powerful— but all share in common their domination by a Great Old One (usually the King in Yellow, but others may be involved). They usually take the form of a bloated or withered corpse, typically wrapped in stained bandages or wrappings, exhibiting odd discolorations and mutations. It is common for a Mythos undead to have one of its limbs transformed into a tentacle (which still functions as an arm), their tongue or other organ extended to great length, or other similar distortions.
Each Mythos undead creature is a unique manifestation of undeath, defined primarily by its abilities and nature when it lived. Most Mythos undead are, to one degree or another, insane—and this insanity continues to drive them in their unlife, preventing purposeful altruism or all but the most unlikely acts of kindness. The vast majority of Mythos undead who do not directly serve the Great Old Ones are chaotic evil or chaotic neutral, while those who serve the Great Old Ones themselves tend to share their patron’s alignment exactly.
