The second of two children, born while Teala was a toddler in their Vortal Construct, Leif - or, as his color designation would call him, 'leaf' green - takes greatly after their father Turquoise. He is strongly gifted with the 'psychic suite' of mental abilities, and doesn't have as much of the 'electrical' nature as his sister. As they grew up together he was always slightly more physical, he's taller and built more muscular than Teala, so that follows. This was all only apparent after he started shooting up in height around age eleven.
In his youth, however, Leif followed in his sister's footsteps, right through portals and doorways, into the unknown with wide eyes and an open mind. He would climb into cabinets and come out in another dimension, which made games of hide and seek with him ... challenging. Though he wasn't precisely the kind of kid you'd need to put a harness and leash on, that was only because Teala was able to follow him into those child-sized portals he made.
Even grandpa Keenan is impressed with his abilities, and not just his dimensionality. Being able to read Vortal auras so thoroughly that he can manipulate them is something that precious few Pantheon or even his own breed the Convocation can do. At first just masking his own presence from view - Vortal or otherwise - but later figuring out how to duplicate Teala's energetic aura, these things are ones he will be able to exploit when he gets going against the Combine or virtually any other enemy. Woe to anyone he wants to gang up on, really.
Leif learned how to follow Vortal trails, left mainly by his sister, but sometimes by his parents, or other visitors to their construct-home. Though he's spectacular at hiding in those games, when he seeks... he wins. Every time. Observant and clever, sometimes less careful than he ought to be, Leif has a love of exploration that cannot be stopped.
When they announced the siblings would be going to Carramba High for their more conventional education, Leif was thrilled. He'd heard Turquoise talk about the place, and was over the moon when they did get to tour it for their orientation. Though he'd been home-schooled with Teala and afforded specific downloaded skills for language, basics such as early math and science, and some small amount of local history (local... to Rookery Earth that is) he quickly took to the more structured and social nature of a conventional high school.
The only classes that he and his sister share are Nexus Geohistory and Cartography, and he is quite good at both of those subjects. They independantly achieve very good scores in either of them, and since their notes and presentations are often quite different, no one can suggest they cheat off one another.
He enjoys reading advanced literature in his Honors English class, though he does have to admit that while it's not 'boring', it's definitely not 'relevant' to his family or their needs. Miss d'Ouberville has had words with Leif's parents regarding his... rather aggressive use of telepathy, even in her class, and though he gets technically good scores on testing for it, in practice - he is definitely up in people's brains way too often.
Where all of his real concentration goes, is into a suite of classes that he feels are connected. From his Urban Exploration class where he learns how to physicall traverse modern cities and ruins alike, to the unusual Time Travel Mapping course that allows him to both show off and exploit existing mechanical devices to travel... To the Personal Space Creation class taught by grandpa Lane, he adds in a decent mixture of skills taken from his Interior Design class. He's visited Keenan's personal constructs often enough to understand that some people have style, and others... not so much.
And yeah, that means he's gone into grampa Lane's personal space and actively judged it lacking in detail... Because it is. Let's call it 'bland'. Though Leif is not going to be getting awards for his own use of decorative design, he's certainly not going to slap up a couple walls and an indistinct ceiling and call it 'done'. He wants a little more flair, and he has a wide variety of 'subjects' that he can take that inspiration from when he's doing his own Constructs.
His after-school efforts border on 'superheroics', since he can use his Aura Masking ability to move powers around - the local Supers council has been watching him for a while, and if he doesn't do something else with his life (well, dragons? they can coexist with superheroics as far as they're concerned) they would love it if he'd come and train young heroes in teamwork and understanding one another's powers.
Did you say dragons? Why yes. Grandpa Lane's wonderful little black dragon Denhadarvahth participated in a mating event that has led to a lot of little eggs, that will surely produce a lot of little dragons. Will one of them be for him or his sister? Maybe both? Hopefully both! Leif is excited to go to Isla, he's enjoyed the additional courses for learning about dragon anatomy and health, their communication, and their travel powers.
