Affiliation: College Arcanum
School: Abjuration
Status: Lost
Iozahn Tower was the ancient tower of Abjuration constructed by the College Arcanum near its founding and named for the first Master of that school. Its present location and condition are unknown. Surviving descriptions portray it as the most overtly defensive of the Eight Towers and as one of the College’s principal historical centers for containment.
Architecture and Study
Old records describe Iozahn as broad and heavily built, surrounded by multiple walls, courtyards, and deeply layered internal divisions. It had relatively few exposed windows and unusually extensive foundations. The design reflected its role as a place expected to contain dangerous magic as often as it was expected to repel attack.
Its scholars specialized in wards, counterspells, barriers, curse-breaking, magical suppression, resistance to planar intrusion, and defensive magical architecture. The College also sent unusually dangerous objects and phenomena to Iozahn when the first requirement was reliable containment rather than convenient study.
Defenses
Iozahn’s outer protections interfered with unauthorized teleportation, remote magical observation, summoned creatures, planar passage, and hostile effects crossing established ward boundaries. Deeper layers could disrupt active hostile spells and make unauthorized magic progressively more difficult to sustain.
The effect was not a permanent antimagic field. Iozahn remained a functioning center of magical research and could distinguish recognized practice from hostile intrusion. Like the other ancient towers, its defenses depended on contextual recognition that the modern College cannot reproduce fully.
The tower could isolate itself internally. Separate laboratories, archives, living areas, and containment chambers were divided by independent barriers capable of closing even after another part of the structure had been breached. An attacker who crossed one layer gained no automatic advantage against the next.
Its defining emergency state was known as the Seal. When invoked, external teleportation, planar passage, magical communication, and most movement between major internal sections could cease. Iozahn effectively became a collection of sealed fortified compartments surrounded by overlapping abjurations.
The Seal was designed as much to contain internal danger as to stop an outside enemy. Historical warnings assume that the greatest threat might begin in one of the tower’s own laboratories or vaults. A Warden could therefore sacrifice communication and mobility throughout the site in order to ensure that something already inside did not escape.
The Warden and the Tower
Historical Iozahn Wardens were required to possess unusually strong affinity for Abjuration. Their attunement progressively removed outside support, easy retreat, magical communication, and protective assistance until the candidate had to maintain a precise containment boundary under increasingly constrained conditions.
The tower possessed the same limited magical awareness attributed to the other original towers. Records describe barriers refusing to open for people who technically held valid credentials but whom the tower appeared to regard as dangerous, although later historians disagree over how literally such accounts should be read.
Disappearance
Iozahn was lost during or around the poorly documented internal fracture that also preceded the disappearance of Staras Tower, Vrahith Tower, and Hechizos Tower. The College does not know whether Iozahn was destroyed, seized, hidden, or sealed.
One persistent theory holds that the tower itself entered a form of the Seal and never released it. If so, Iozahn might still exist behind its own defenses, isolated from the wider world by the very system designed to preserve it. No evidence has confirmed the theory, and College histories treat it as one possibility among several.
