The Keeper true identity

The gigantic white beam streaks toward the abomination, but it strikes an invisible shield surrounding the creature. Like a stone thrown into calm water, the shield flickers and ripples, but Daniel knows it's still intact.

He notices that the shield doesn't just resist the attack—it absorbs the power of Baltruse's blast, like a vast lake swallowing a stone.

Daniel sinks his mind into his mindscape to analyze the abomination. Under the mindscape's vision, he notices that the abomination doesn't have any enchantments he can target. This suggests that the abomination might have the same status as a "player" in terms of the game's rules.

But if that's the case, the abomination should have taken some damage, not remained completely immune. Daniel knows that the beam Baltruse unleashed earlier represents its ability to destroy one target creature. However, in the real world, the rules aren't as clear-cut as in the game, and it can't outright kill a "player."
