The Holy Triad

Overview
The Holy Triad is the name of the combined forces of the first Human, Dwarf and Elf. The Gods combined their powers to create these Demi-Gods to help them in defeating the overwhelming threat, Annihilus, during the Dark Ages. The Gods created these three holy beings 10,000 years after Annihilus sent the world into the Dark Ages billions of years ago. The first human was called Brugnem Senkrit. The first dwarf was called Dazzag Steelspine. The first elf was called Lilith Kelro. The Gods had created the first humanoids in the form of a Human, a Dwarf and an Elf, the Gods combined powers also meant they each had Godly powers and were physically tough becoming the first Demi-Gods.

History
Once Annihilus had created undead the Gods realised the extent of Annihilus' power was growing too powerful and too quickly. So the Gods decided to merge their powers and create a powerful force to fight the undead for them. They created the Holy Triad and these three Demi-Gods were believed to be the ones to finally defeat Annihilus and his undead hordes but after around 40,000 years of fighting they were overwhelmed and succumbed to Annihilus' whim and became the first humanoid undead, The Deceased Triad.

Annihilus led the Deceased Triad into battle swaying the odds in his favour. The Gods had underestimated Annihilus' power and were unable to create beings powerful enough to stop him. A second attempt was made to destroy Annihilus and this was done by the Gods combining their powers. They created people in the image of the Holy Triad. As the Gods had used up the majority of their powers to create three powerful Demi-Gods they were unable to create such powerful beings again, as Annihilus was already siphoning their powers as well, so they created the first three races, Humans, Dwarves and Elves. The Holy Triad were used as an image for the races to put their faith in. The humans worshiped Brugnem Senkrit. The Dwarves worshiped Dazzag Steelspine. The Elves worshiped Lilith Kelro. The races that the Gods created were used to fight Annihilus' undead hordes in separate corners of the world this battle became known as the Siege of Horrors, the first battle to be fought by humans, dwarves and elves. The races fought against the undead and the Deceased Triad but the Triad were too powerful for the races to defeat so the Gods intervened. It isn't clear if the Gods destroyed the Deceased Triad but they were not present for the rest of days.
