Professor Garcia was indeed lecturing at the moment, and Shard thought maybe he should turn the gaslight up a bit to make the place more like a classroom:
"As for the rules of the Time Key, they were mentioned in your 'Theoretical Basis of Time Travel' course. Moreover, you needn't worry about any trouble caused by time travel; our world is not as fragile as you imagine, nor are mortals as powerful as they believe themselves to be. In a world where thought can affect matter, it is the world itself that is the most powerful. Now, please take the key out of the basin."
With a few words, he resolved all of Shard's doubts, which were probably similar to those every student had during their first time travel.
"The basin?"
Shard looked at the basin glowing with a soft light, squatted down and dipped his hand into the water, which was warm for some reason, and indeed retrieved a key.
