I've been doing (very admittedly off-model) character reference sketches of other OCs that will be featuring in Airi's story, and I had in mind an art piece of one who serves as her teacher - a reversal of the Old Master trope, where it’s a young girl that is actually Really 700 Years Old/Older Than They Look.
This is Iryna, pictured here with the ghostly shade of a large wolf familiar who fell in battle against the criminal elf cartels and had his domain exploited of resources. He responds to the name Lupara, yet no one is certain if that is his real name. Although he holds distrust towards earthwalkers, he aligns himself with Iryna for a goal they share: vengeance - and justice - toward the cartels for the crimes they have committed against them.
History books do not say what became of Lupara; for elementals, death is not the end, and death surely should not stop Lupara from becoming praja, or magic, made manifest. It can be assumed that after their journey he remained with Iryna as an equal and mentor, observing man and familiar and demon in their explorations.
As for what became of Iryna...well, that is a story for another day.
