The staff played a central role in the Imperial Simulacrum. Jagar Tharn wielding the Staff of Chaos (Arena) Mournhold's rulers responded that High King Moraelyn himself had placed the Staff in the keeping of the ancestor god Ephen, and Mournhold was arguably the god's birthplace. Įbonheart remained jealous that the Staff's safekeeping was assigned to the rulers of Mournhold, and not to his own fief, and claimed that rightful guardianship of the Staff of Chaos should have been entrusted to Ebonheart's house. Additionally, Symmachus later became the Prime Minister of Mournhold. This Ra'athim was later rewarded for his allegiance during the war, with Ebonheart becoming his own fiefdom. Symmachus was responsible for placing the Staff back within the anvil and resetting the repository statue with the help of the Ra'athim. It was decided that the Staff of Unity and Chaos should be locked away where the Horn had laid.

The stone came to life and struck an accompanying anvil, releasing the Horn, which Tiber finally claimed. To the unanimated statue, the Ra'athim by blood would have said the required words to unlock its treasure: noting his bloodline traced back to Ephen and Moraelyn, and that at Resdayn's last need, he requests the guerdon which Ephen guards. Symmachus, having been a miner of the city in another life, was likely invaluable in guiding them to the Horn's hiding place: an ancient shrine dedicated to the old ancestor god Ephen. Emperor Tiber, General Symmachus, and the Ra'athim rag-tail, to have acquired the horn, these three would have had to have Mournhold's mines. Presumably, Emperor Tiber came himself after the sack to claim the Horn of Summoning, a veritable super weapon he could've used as leverage against the resistant peoples of Resdayn, to force the Dunmer to sue for peace.

In one of these battles, Almalexia City and its Mournhold district were laid waste. There were several battles in the Septim Empire's conquest of Resdayn. Sometime during his conquests (perhaps during the one of relevance), Tiber allied with himself with a male member of the Ra'athim lineage, who was on the rag-tail end of the family, but he was their kin nonetheless, which is all Tiber needed.

However, we do know where Tiber chose to discard it. How the Staff of Unity and Chaos passed into the hands of Emperor Tiber Septim is unknown.
