Embedded Arrays

Lassim awoke before the first light of dawn once more, a deep sense of satisfaction lingering from last night's breakthrough. Though he'd barely slept, his mind was buzzing with energy as he rose to get ready.

He quickly gathered his things and his notes from last night's success at elemental fusion and memorized array sheet. 

Going down the stairs and stepping out of the house, he followed the path in the quiet courtyard with a distracted gaze, his thoughts momentarily drifting back to the crackling orb of fused energy he had managed to form last night. The feeling of holding lightning and water mana blended together in harmony, however brief, had been exciting.

He entered the workshop to find Rlyis already at her bench, carefully arranging her tools and preparing them for today's work.
