Zyvie Setie is an ancient research center in the Thangolos Forest. It was built by a labor force serving a primordial named Asoun. When the Womb of Entropy was destroyed in 1271 LE, this research center vanished. Magically hidden, it was warded with spells that convinced even the strongest of minds to go elsewhere.
In the Year 1500, Asoun dispelled the magic hiding his secret hold. He then had his agents spread rumors of entropy fragments stashed somewhere in the Thangolos forest. This led to conflict as various groups tried to secure Zyvie Setie. This conflict, the War of the Fragments (1500 - 1512), would see the construction of an Entropy Arch, and bring about a change of worship in the Altocumuli Empire.
Not long after the war, for reasons still unknown, Altocumuli abandoned Zyvie Setie and all claims over the reputed Entropy Arch within. Guardians of rifts and such things, today this place is under the protection of the Portal Sentinels.
