Bio[edit]
Nothing can stop us. Nothing can slow our march. And when we have arrived, all will burn.▶️Vrogros, the Underlord
Aliases:
Pit Lord, Azgalor, UL
Lore:
Neither myth nor song exist to tell of their coming.
Deep below the surface of the world lay unknown wonders and horrors. Down and down again, well beneath the slithering magma fields and simmering roots of dormant volcanoes stands the obsidian city of Aziyog, its incomparable stonework spanning an endless cavern. Within honeycomb walls mortared with the bones of countless slaves lies the domain of the Abyssal Horde, and their brutal underlord Vrogros.
Armed by the monstrous forgemasters of his kind and well-practiced in the arts of the Dark Rift, Vrogros is able to conjure forth flame and crippling malice through the twist between worlds. He seeks always to expand his holdings, destroying or enslaving all he encounters. Yet the lands offered by the subterranean realm are few, and so his sights have turned upward. By his command the first waves of abyssal invaders have already marched through the rift, a few doomed legions meant merely to test the might of nations above. Now, as his full force readies itself for unending conquest, Vrogros himself steps into a sunlit world to announce his coming reign. Those who face the Underlord will bow and pay tribute, or be crushed where they stand.

Trivia[edit]
- Prior the June 23, 2016 Patch, Underlord's title was Abyssal Underlord. The reason for this change us unknown.
- According to the Bastion Announcer, ▶️ "Pyre Lord" was also a proposed name for Underlord.
- Underlord had been developed since 2012; he already had a beta model, placeholder ability icons and fully finished and working abilities. He could also be spawned in lobbies with cheats enabled for a short while before it was disabled.
- This suggests that his release was originally planned much earlier (as a comparison, all other heroes were released shortly after their files were added to the game), but was delayed for reasons unknown.
- Before his release, Underlord was showcased at the All-Star match of The International 2016, played by N0tail. He originally picked Sand King, but a bit after the start of the game, SirActionSlacks replaced his pick to Underlord.
- After killing Bane, ▶️ "You have my permission to die.", is a reference to the famous line "When Gotham is ashes, you have my permission to die", said by the villain Bane from the movie "The Dark Knight Rises".
- When casting Dark Rift, ▶️ "Hold on to your butts!", was spoken by Samuel L. Jackson's character Ray Arnold in the movie "Jurassic Park (1993)".
- Underlord was the final "DotA" hero ported over, before "Dota 2" began to feature original heroes.
- Warcraft 3 similarities:
- Underlord's hero concept is originally based on Azgalor, a campaign-only variant of the neutral Pit Lord hero.
- In DotA, he was also named Azgalor, the Pit Lord. Both his name and title were changed in Dota 2 to avoid copyright issues with "Blizzard Entertainment", since the Pit Lords are an existing race of demons in the "Warcraft" universe, with Azgalor being a known name amongst them.
- Firestorm's core ability is based on Rain of Fire, the main difference being that the latter is a channeled ability.
- Atrophy Aura's base concept is inspired by Howl of Terror, which is an active ability that reduces enemies' attack damage.
- Pit of Malice was originally inspired by the Graveyards, an Undead building.
- Like the Graveyards, Pit of Malice creates a ring of obelisk headstones around the target area.
- In its original iteration, Pit of Malice also used to create corpses within its area, just like the Graveyards.
- This was also the inspiration of Underlord's old ability, Expulsion, which utilized those corpses.
- Dark Rift's base functionality was based on the Archmage's Mass Teleport, the main difference being the latter being a channeled ability.
- Fiend's Gate draws inspiration from the Dark Portals within the Warcraft universe, which are gates that connect two worlds, used by the Pit Lords and other demons to invade other realms.
- Underlord's hero concept is originally based on Azgalor, a campaign-only variant of the neutral Pit Lord hero.
