For timeline notes: Runaan is approximately 19 here. Ethari is at least 25, with his horns at full adult size to Runaan's young adult. Runaan is a full-fledged assassin and has been for four years, and Ethari has been a smith for at least a decade, since Moonshadow appear to reach majority at around 15.
The last figure through the door was taller than the others, even Radnaal. Most Moonshadow were slight and lean, even the taller men barely rising to Ethari's shoulders or jaw, but this man was nearly of a height with him. His horns were relatively small, betraying his youth, but arched and twisted proudly up and back like a dragon's, a gentle curve at odds with the severe lines cut by the tattoos across his delicate nose. He had a soft jaw, hair nearly to his trim waist, and his eyes -
Oh, his eyes. A pretty, piercing turquoise that caught Ethari's entire attention immediately when they lit upon him, widening at the sight of him. Framed with kohl that highlighted his long lashes, brought to a point that only highlighted how large and soft those eyes were, angled slightly in his youthful, delicate face, sparking with something and widening further as he realized Ethari was watching him move.
