Dhakoth

Cold, manipulative, and utterly evil, Dhrakoth represents the pinnacle of undeath. Dhrakoth resembles a black dragon with scarred, oozing, membranous wings. The creature's empty eye sockets pulse with sickening green light.

Dhrakoth speaks the draconic tongue common to all evil dragons. In addition, it can communicate with any creature with a connection to the Negative Energy Plane.

Society
Dhrakoth makes its home in ancient underground tombs, slowly exerting its evil influence over the rotting corpses buried within. In fact, Dhrakoth can animate dead as often as it wishes, limiting the size of its undead army to the availability of corpses.

Born in the heart of the Negative Energy Plane, Dhrakoth's essence was fused with a corporeal dragon through Tiamat's dark magic. The foul creature once served Tiamat unswervingly. As Dhrakoth's power grew, however, it began to seduce several of Tiamat's key generals. The small but powerful cadre seceded from Tiamat's court and began a centuries-long campaign to annihilate every living thing in the multiverse.

Although still fiercely independent, Dhrakoth has recently sealed a pact with the court of Tiamat. Thus, the creature bides its time, building its dark forces until Tiamat is ready to begin her conquest of the multiverse. Though a potentially unstoppable pair, these two dragons hold no love for each other. Tiamat knows that Dhrakoth's ultimate goal is the destruction of all life - including her own - and has set several of her servants to watch this necromantic beast for treachery. Dhrakoth, for its part, feels that Tiamat's resolve is weak, and it plots to overthrow her and assume her role as the ruler of all evil dragons.

Ecology
As an undead creature, Dhrakoth does not require physical sustenance. Rather, the beast feeds on the life energy of its victims. As a result, any creature slain by this undead monster cannot be raised from the dead, resurrected, or wished back to life. In addition, the spirits of these unfortunates cannot travel to the plane of their alignment upon death; they are irrevocably destroyed.

Relationships
Dhakoth is the son of Tiamat.
