The Hidden Armigers are the intelligence arm (spy network) of the Ebonheart Pact. It is rumored that they were once an alchemy group within House Telvanni. They defected and now answer to King Jorunn.
The Hollow are stone constructs created by the Wilderking as a form of resurrection. Their purpose is to protect Greenheart from those with malicious intent who would seek to enter the Wilderking's domain. They are unthinking in their duty, and as such they can be encountered as enemies in certain areas. They are considered undead (meaning they are affected by the Fighters Guild skill line) and drop Elemental Essence upon death.
The Hollow Moon is a charitable organization of thieves operating at the Redfur Trading Post. They steal from wealthy merchants and give what they take to those in need. Be it gold to buy food, silks to trade for other goods or gold to buy food, medicine for the sickly, etc. The Hollow Moon often clashes with Jode's Chariot, the local law enforcement group. The two organizations generally have mutual respect one another, as they both agree with the premise of giving to those in need. However, the Hollow Moon must still be light on their feet, as Jode's Chariot is contractually obligated to stop thieves by Shan-ra, the leader of the merchants running the trading coster.
Agents of the organization will often give Hollow Moon Tokens to the infirm so their need is not questioned when they petition the group for aid.

The Hounds of Hircine are a group of legendary hunters. They honor Hircine, the Daedric Prince of the Hunt, and take their name from the Hounds that accompany Hircine on his hunts.

They have a long tradition in the mercantile and maritime pursuits, and are one of the richest Houses in High Rock.
House Dres is one of the Great Houses of Morrowind. They controlled the southeast of Morrowind from Tear. This position allowed them to act as the main slavers for the rest of Morrowind. They were opposed to the Ebonheart Pact's terms, which freed all Argonian slaves. However, unlike the other three Great Houses which belong to the Pact, the Dres still keep non-Argonian slaves in the territories they control. They have strong ties to House Indoril. The House is ruled by Grandmaster Omin Dres from his palace in the Dres city of Kragenmoor.
House Hlaalu is one of the Great Houses of Morrowind. Their capital of Narsis, on the banks of Lake Hlaalu, is an important trade city. Their main priorities are business and trade, making compromise a way of life, thus they had no real objection to the Ebonheart Pact, rather they saw it as an opportunity to open more trading routes.
House Indoril is one of the Great Houses of Morrowind. Their capital is Mournhold, which is also the capital of the Ebonheart Pact. The House is ruled by Grandmaster Tanval Indoril, who resides in the Indoril city of Davon's Watch. The Vanguard are a subfaction of this Great House.

High Councilor Meriath rules as the House's Archmaster.
House Telvanni is one of the Great Houses of Morrowind. They refused to join the Ebonheart Pact, partially on the grounds of slavery, as the Argonians, which make up a large proportion of their slaves, were granted equal membership of the Pact and all Argonian slaves were to be released.
The Huntmasters are a group primarily consisting of Altmer that venerates Hircine. The order's leader, Lady Ghisiliane, hosts a Great Hunt to amuse bored nobles. They use not only exotic animals for the hunt, but mortals as well. The Huntmasters kidnap people for this purpose.
