It was just 3 words. Three teeny-tiny words that made him happy and it wasn't the stereotypical "I love you," it was person introducing themselves.
"I am Mumbo"
And yet, to Grian, they held so much more meaning.

Grian was completely speechless, fumbling for the right words to say before deciding none of them were correct and hugged Mumbo, his smile as bright as the stars that now shone through the window. Tears of happiness gathered at the corners of his eyes, spilling over as he laughed at the ridiculous of crying from being so happy.

Mumbo wrapped his arms around Grian, offering a gentle squeeze before pulling back, understanding why his 3 words stole all of Grians.

So many words raced through the pranksters mind, sentences stampeding, trampling each other until his brain was a rush of white noise. None of the words felt right, properly voiced how happy he was or how grateful that he had Mumbo at his side. That he was so grateful to have the redstoners trust like this. That he wasn't alone.

"I trust you, dude." Mumbo smiled at the faerie who was floundering for words. "I know you won't hurt me."

"Thank you." Grian managed to stammer out, still grinning like an idiot. "I'm Xelqua."

And just like that, the joy in the atmosphere shifted to confusion.
"What?"

"Well, since you gave me your name, I figured I'd give you my true name. Make it even and all that." Grian shrugged. "But by all means, keep calling me Grian. It's weird to use true names. A lot of fae have nicknames or other names we go by." He shrugged nonchalantly.

"Wait hold on- what's a true name and how is it different from a regular one?" Mumbo asked.

He looked up at Mumbo with a small bit of surprise, as if he couldn't believe that Mumbo didn't know the difference.
"A true name is more powerful. Knowing it is incredibly hard and giving it up means that whoever knows it can control that person." Grian explained sheepishly, glancing off to the side. "A regular name allows for some control, but not completely like invoking a true name would.
"It's why people say to not give your name to a fae and that names have power."

"Right." He replied, nodding. "Makes sense."
And still, now knowing the weight of a name, Mumbo found that he didn't regret a thing.
