To know who Ius the Agitated is, one must look back to the first two entries in the Elder Scrolls series: Arena and Daggerfall. In The Elder Scrolls I: Arena, the Palace of Rockpark has its entrance blocked by a blacksmith's shop known as Unearthed Equipment. A simple bug of the procedural generation, right? 

WRONG. In the Elder Scrolls, EVERY bug is in fact a specifically crafted FEATURE!

In Daggerfall, a book dubbed "Ius, God of Animals" (link) may be found that explains that the shop was, in fact, placed there by the patron deity of animals, Ius, as a punishment to a cruel king who abused a wombat. Moreover, Ius is said to be worshipped throughout the land, as statues to his greatness can be found throughout Arena (perhaps, retroactively, what was once a piece of setting dressing became the visage of a dark, malevolent god).  

In 3e427, however, Ius' worship has taken a different turn. His statues depict a misshapen humanoid holding a set of balancing scales that are alight with fire, but no one knows why, and at this point in time, no one cares. His tome was an amusing manuscript, but Ius' worship evidently fell out of favor, as he was never mentioned again in an Elder Scrolls game since Daggerfall. This mod changes that. 

As the Champion of Ius the Agitated, God of Animals and Extremely Fickle Curses, it is your job to not only restore Ius to his former station, but to take his unique artifact, the balancing scales known as the Adjudicator of Ius, and increase its power through the course of the mod's questline. What's more, Ius and his power are malleable to YOUR actions: if you choose to be merciful, the scales will reflect that. Solve every problem by burning everything to the ground? Ius' artifact will become more devastating and deadly as a result. It is ultimately up to you whether or not Ius' magnificent return to glory is a brutal or merciful one.
