This is meant less as a formal story and more as an intro to Elena.
Winter 1240
As snow falls outside the Mercere Tower, Lucas waits beside the Mercere portal to Harco. Today was the day the letter said that Elena would arrive, and he was never going to get anything done while he was waiting for his new apprentice to arrive. He'd tried starting on Atlanticus this morning. But after reading the same paragraph seven times, he had to admit that he was too on edge. After all, he'd be bound to Elena for the next fifteen years. That was longer than he'd have spent with any of his own children, three of whom were off to Redcap training no later than age twelve, and the fourth of which was going away next year at age ten. From what he'd heard, Elena was a good fit for him. But you never could tell for certain until you were in the apprenticeship. And then it was too late - well for him at least. One did not give up a Mercere apprentice in any but the most dire circumstances.
Will you stop pacing, Horus thinks to him from his perch on a nearby window. That's not going to get her here any sooner, and it's just going to work you up.
You're right, the magus thinks back, taking a deep breath and engaging in a meditation exercise he learned during his own apprenticeship. But if it makes you feel any better, I was just as nervous before I was bound to you.
Lucas then takes a seat on a bench set against the wall and begins chat with the Redcap on duty, Gunnvara in this case. It's clear to anyone that he's distracted. But he does his best to keep up his end of the conversation. This goes on for about an hour until without warning the portal starts to activate. A moment later, a link is formed with Harco and two people step through from that far-off covenant. One is an older woman - clearly a Redcap; the other is a young girl of perhaps ten years with long, dark hair.
"Good morning Lucas," the woman says. "Good morning, Gunnvara. "I didn't expect a welcoming committee." She smiles and looks down at the girl by her side. "Lucas, this is Elena. Elana, this is Lucas."
"Good morning," Lucas replies with a bow of his head. "It's a pleasure to meet you. Welcome to Andorra. And may I formally offer to teach you the Hermetic Arts."
That's it, he thinks. There's no going back now.
