Chapter 6: The Mysterious Rune

After the duel, Skully and I returned to my dorm room to celebrate our victory. But as we examined the *Tome of Summoning Secrets*, something caught my eye—a strange rune etched into Skully's ribcage. It wasn't there before the ritual.

"Skully, what's this?" I asked, pointing to the rune.

He glanced down, his eye sockets narrowing. *"Huh. That's new."*

I flipped through the tome, searching for an explanation. The rune matched one in the book, labeled *"Mark of the Ancient One."* According to the text, it was a symbol of immense power, bestowed only upon the most legendary summons.

"Skully, do you know what this means?" I asked, my voice trembling with excitement.

He shook his head. *"Not a clue. But it looks important, doesn't it?"*

"Important? This could change everything!" I exclaimed. "If you're marked by the Ancient One, you're not just a summon—you're a legend in the making."

Skully grinned, his jawbone clacking. *"Guess that makes me even more awesome than I thought."*

But as I read further, my excitement turned to concern. The text warned that the Mark of the Ancient One came with a price—a burden that only the strongest could bear. It didn't specify what that burden was, but the ominous tone made me uneasy.

"Skully, are you sure you're okay?" I asked, studying him closely.

He waved a bony hand dismissively. *"I'm fine, Master. Better than fine, actually. I feel… powerful. Like I could take on the world."*

I wasn't convinced, but Skully seemed determined to brush off my concerns. He spent the rest of the evening practicing new spells, his rune glowing brighter with each one. But as I watched him, I couldn't shake the feeling that something was off.

Later that night, as I lay in bed, I heard Skully muttering in his sleep. His voice was low and guttural, unlike his usual cheerful tone. I sat up, my heart pounding, and saw his rune pulsing with an eerie light.

"Skully?" I whispered, reaching out to shake him.

He jolted awake, his eye sockets wide. *"Master? What's wrong?"*

"You were… talking in your sleep," I said hesitantly. "And your rune was glowing."

Skully looked down at his ribcage, his expression unreadable. *"Oh. That's… weird."*

"Are you sure you're okay?" I pressed.

He nodded, but there was a flicker of uncertainty in his eye sockets. *"Yeah, I'm fine. Just… tired, I guess."*

I didn't push the issue, but I couldn't shake the feeling that something was wrong. The Mark of the Ancient One was more than just a symbol of power—it was a mystery, and mysteries had a way of unraveling when you least expected it.
