A devotee of Yredelemnul that has committed to eternal worship and servitude - even beyond death.

Unborn are liches who boast powerful Necromancy along with an extremely dangerous ability to reflect damage back at you.

Spells

Living characters facing unborn should definitely bring at least one rank of life protection to negate Agony. Undead characters can rely on summoned hordes to block the line of fire necessary for Dispel Undead to hit you. Abjuration can exorcise whatever horrible things Haunt surrounds you with. In the end, though, Mirror Damage is still the most dangerous spell they possess.
As with the deep dwarf death knight, when an unborn "kneels in prayer and is bathed in unholy energy," that means it has activated Mirror Damage. In the console game, its glyph will change from a steady brown L to an alternating purple L and grey L. You can also see if mirror damage is active by examining the unborn to see if it is "reflecting injuries." The spell lasts approximately 20 turns.
When an unborn is reflecting damage, do not hit it with any big Conjurations. Even if it isn't reflecting damage, don't use any massive multi-turn spells like Ice Storm, Fire Storm, or Tornado, as it may turn on reflection halfway through the spell. Instead, snipe at it while it is not reflecting, or use summons to take it out.

Prior to 0.13, this monster was called Unborn deep dwarf.
