Hythloth

Hythloth [hith-loth] is a dungeon located on the southern shores of the Isle of the Avatar, near the Shrine of the Codex. One of the eight infamous Britannian dungeons, Hythloth is historically associated with the virtue of Spirituality.

Ultima IV
Hythloth was formed around the time of the christening of Britannia, and in its earliest incarnation, managed to span a large portion of the globe – having entrances on both the Isle of the Abyss and in the environs of Castle Britannia itself. During the Stranger's pilgrimage toward Avatarhood, the hero would have occasion to traverse Hythloth, entering the secret passages within Lord British's castle that led to the dungeon's deepest reaches and later emerging to find the lighter-than air device.

For reasons never made clear, the White Stone of Spirituality was missing from its altar within Hythloth during this age, have come instead to rest in a small basin in the Serpent's Spine mountains. Within Hythloth, however, an adventurer could still find numerous magical orbs that gifted those who touched them with supernaturally enhanced strength, intelligence and dexterity. At its lowest level, Hythloth was connected to the Altar Rooms of Truth, Love and Courage, which interlinked it with the dungeons Deceit, Despise, Destard, Wrong, Covetous and Shame.

Ultima V
After the Codex of Ultimate Wisdom was taken from its seat in the Abyss, the Great Council placed a seal over the major dungeons, including Hythloth, in the hopes that they could confine the beasts that lay within beneath the soil. This, however, had the unforeseen outcome of creating a vast and expansive Underworld beneath the earth, fostering a sprawling haven for the monsters the council had sought to banish.

After Blackthorn's rise to power, however, the members of the council were named outlaws, and suffered grievously at the hands of the Oppression. As such, the returned Avatar had to search out the imprisoned Hassad, who lay captive in Blackthorn's dungeons, so as to gain the Word of Power that would reopen Hythloth: Ignavus. Once armed with this knowledge, the hero could use the dungeon as a means of reaching the Underworld below, finding its caverns now opened onto lands near the Shard of Cowardice, which had birthed the Shadowlord Nosfentor.

Ultima VI


As the collapse of the Underworld instigated the subsequent destruction of the Gargish homelands, Hythloth alone remained open to the lands that existed below and by the time of the gargoyles' war on humanity, it had become the sole means of reaching their crumbling homeworld. During this time, the scholar, Captain Johne, had taken residence in Hythloth's tunnels, where he had been making a study of the Gargish language through his friend, Beh Lem. The Avatar would eventually have cause to pass through here and to seek Johne out, as understanding the words of the gargoyles would be crucial in forming a lasting peace with them.

Ultima VII
During the Fellowship's rise to power, the group saw fit to prepare Hythloth as a base of their operations, filling its passages with a hidden compound that housed numerous followers of the Guardian. Within its deepest recesses, they erected a chamber to house the Black Gate, through which their master was intended to pass into the world of Britannia.

As the Avatar came to understand the Destructor of Worlds' intentions for the realm, the hero was driven to confront the Fellowship elite deep within their fortress in Hythloth, killing numerous members of the group's inner circle before eventually shattering the blackrock moongate in the very moment it became permeable, thereby barring the Guardian's entry into the world.

Ultima IX
During the Avatar's last journey in Britannia, a dungeon known as "Hythloth" could be found near the waters of New Magincia, rather than upon the Isle of the Avatar, perhaps having been some reemerged remnant of the tunnels that once connected Hythloth to Castle Britannia. The returned hero would have to navigate this sewer-like maze (which now appeared to be juxtaposed with the virtue of Humility) to return to the surface following the destruction of the Gargish underwater city of Ambrosia.

Trivia

 * Hythloth derives its name from hylotheism, and for its first appearance in the Apple II version of, it is styled as "Hylothe." In all further ports of the game this was changed to "Hythloth," the spelling maintained throughout every subsequent Ultimas in which the dungeon appears.
 * In Runes of Virtue, the Cavern of Pride also served as an underwater trans-oceanic tunnel leading to the Isle of the Avatar. Delving into its dark recesses, the hero located the Rune of Spirituality, as well the famed Mystic Sword.  Further adventuring would also reveal the magic Troll Ring, which would disguise the hero as a troll so monsters would not attack.
 * In, the Cavern of Pride was located in the village of Cove, which had been overrun by a powerful liche. The dungeon could be reached upon the liche's destruction.  Within these depths, the hero would find powerful magic armour, a magic sword, a ping pong paddle, as well as the powerful star wand, which granted access to the Great Stygian Abyss.  At the bottommost level, Quenton, the mayor of Skara Brae could be rescued.
 * In earlier drafts of from Bob White's tenure as lead designer, Hythloth appeared as a labyrinth of natural tunnels spanning the oceans of Britannia to connect the underwater Gargish city of Ambrosia with Britain's sewer system, much as in previous entries. In this version of the game, the Avatar was to navigate Hythloth in order to return to the mainland after seeking out the gargoyle ruler, Vasagralem, and his loyal subject, Desbet, as they took refuge in their abandoned subaquatic city. The dungeon's cavernous surroundings were subsequently removed in the numerous alterations that preceded the final release of Ascension, with the environment of the former Britain sewers instead adopted as the setting for Hythloth.
 * An entire section of Hythloth in was deemed too difficult by play-testers and the dungeon was truncated. Curiously, however, that section was left in the finished game instead of being deleted or sealed off; there is only an optional transporter disc that allows the player to bypass the final areas.
 * In the openings to Hythloth are blocked before going to Ambrosia but open afterward.
 * In the cancelled Ultima Online 2 and the Technocrat War trilogy, Hythloth was to be included as a dungeon on the southeastern continent of Logosia.
