"Never offend people with style, when you can offend them with substance."

Caelnir grew up in the underdark. He'd heard stories of the sun, of the moon, but he'd never seen them. He couldn't even imagine them.

Then his little brother Kestrel came to live with him. With his fiery red hair, and his golden eyes, and his warm, bright smile, Caelnir felt like he was experiencing sunlight for the first time. Even after they moved from the underdark to the surface, and his eyes struggled to adjust to the brightness of daylight, he always felt like the sun was a candle next to the warmth of his little brother's love.

Caelnir loves the moon. Its cool silver light reminds him of home in some ways, though there's nothing like it in the underdark. He loves to stand under the night sky, face turned up, and marvel at it's beauty.

The first time Astarion kisses him is under the moonlight, his mouth cool as moonbeams against Caelnir's lips. He glows in its light, as if one of Selûne's Tears had come down from the sky to embrace him.

When Caelnir returns to the underdark for the first time since he left almost 30 years ago, he has Kestrel and Astarion at his sides. Their presence illuminates the shadowed corners of his heart, and brings light and joy to the cold darkness of his homelands.

Caelnir is a child of the night, and his brother and his lover are his sun and his moon.
