In the beginning, Ticonderoga created this shard imbuing it with a bit of his personality, the chaotic part. He created four shards in all each one the precursor of the 4 alignments. Before the beginning of time, Ticonderoga created two cosmic apprentices Panagiotis and Panagiota to help him in the creation of the multi-verse. These entities were entrusted with the placement of these corrupting artifacts. This artifact was placed in a demi-plane of pure Lawful energy to counteract it's chaotic properties. The others were placed in their own opposites to counteract their alignment properties as well. Eventually the stress from their monumental tasks intermingled amongst the entities, then spreading to the artifacts and weakening their prisons allowing the artifacts power to escape corrupting the entities. The one in the negative energy corrupted Panagiotis and the one in the positive energy corrupted Panagiota and from that point on the entities lost their absolute neutral alignments, So instead they gained the alignments pure evil and pure good respectively.
They now thought of each other as abominations of their new beliefs and set out to destroy each other. In this cosmos wracking war Panagiota won and killed Panagioti, her brother. Ticonderoga saw this and took Panagiotis' body and used it to create a singular plane of unifying good called Chrysosdom. For Panagiota's treachery he banished her to a place beyond known existence. There she used her knowledge of shard creation to create two shards one of knowledge and one of chaos, but the chaos shard was imperfect and mutated into a shard of madness. The energies this shard produced fused the two shards together into a plane of incomprehensible knowledgeable madness called The Far Realm. To look after this realm Panagiota created multiple deities such as Cthulhu and Hastur among others, all were given the name of the Old Ones. For this atrocity Ticonderoga imprisoned her within a city named Sigil. Eventually her evil alignment wore off and she regained her true neutral alignment. Now today after a millennia of imprisonment she is known as The Lady of Pain giving little thought to the realm she inadvertently created believing Sigil is her one and only true home. Chrysosdom ended up feeling the affects of the original Law and Chaos shards in the north Chrysosdom the Law shard imposed ideals and order. In the south the Chaos shard imposed entropy and disorder. The north is now what we call The Astral Sea and the south is now what we call The Elemental Chaos. The Shard of Pure Chaos’ current whereabouts are somewhere deep in center of The Elemental Chaos in a place it helped create (Limbo) protected by the most chaotic creatures of all time.
