Created on the plane of Axiom, Altaen was the first Inevitable created by Solivagus and the dearest being to his father's heart, if an Inevitable demi-god can be considered to have a 'heart'.
Most of Altaen's eons long existence has been spent aiding his father in what is known amongst the Immortal Initiative as the Great Endeavor, an agenda so reality-shifting that Solivagus and his closest followers were to be destroyed for their transgressions.
Altaen had gotten wind of the assassination plot mere minutes before it occured and hatched a daring raid against the approaching Inevitables. The raiding party destroyed their would-be assassins outright, the concept of geurilla tactics and their application something Solivagus had instilled in Altaen when he was newly built.
In the aftermath, Solivagus and Altaen led their allies through a one way planar portal and masked their journey with all the skill of master sorcerers.
Arriving upon a dying world far from the resource-rich worlds near the core of the Material Plane, the exiles burrowed deep into the planetoid and reached its core within a matter of days. The core of the planetoid was nearly spent, its magnetism and energy all but gone.
Together, Solivagus and Altaen joined their combined Impossible magics and restarted the core. The next few centuries were spent hollowing out and replacing uch of the planet's mass with artificial components for space travel and powerful protective barriers like the Power Grid.
Altaen and the exiles became masters of artifice and navigating deep space and to this day only the Immortal Initiative truly understands the inner workings of Hideaway, their home away from home.
