Valedicero

Background
Orec Idelav was an evil human wizard and conjurer. Late in life, he came to regret his choices. He spent his resources learning how to master the most powerful conjuration in existence: the Wish. He used this spell to send himself back in time to confront his younger self, in an attempt to rewrite history.

The young Orec was shocked to see his older self, but ignored his warnings. He used his elder's moment of weakness to attack and kill him. He stole his magical items and spellbook and used that knowledge to fuel his own power, effectively multiplying his own abilities in a very short time.

He took on the name Valedicero. History would play out largely the same, except later in life he took a different path. Instead of spending his years learning the Wish, he already had access to it. He used its power to start traveling the planes and collecting knowledge. He was especially active in the Astral Plane, where he did not age, making him much longer lived than most humans.

Eventually he was contacted by the Watchtower Arcanist Society. They offered him a position on the council as Grandmaster Conjurer in return for him no longer using the Wish spell. Its power was too threatening, they determined, and wanted to avoid its potential to change history and imbalance reality.

Valedicero refused, but made a different offer. He would use a Wish one more time to summon a younger version of himself that could act as his apprentice. Likewise, the apprentice would hold a position on the council. This would upset the strange balance of the council by adding a ninth member, whom Valedicero thought he could manipulate in his favor. The council debated for some time but finally agreed.

Valedicero summoned his younger self, Orec Idelav. Orec agreed to be Valedicero's apprentice, understanding its opportunity as well as the great power it afforded him by being on the council. He would be its weakest member but have similar influence to them. Despite what Valedicero believed, Orec did not always hold the same views as his elder version. This meant the two of them became key figures on the council as people tried to convince one or both of them to support their ideas.
