장 74: Weaving a story

He began by describing his first step: destroying the fog formation with the help of a non-existent artifact that channelled thunder and lightning. 

He hid his ability to cast large spells temporarily to protect himself. After all, he understood the Tower's nature too well.

Once, they treated him like royalty, showering him with resources, only to discard him like trash when his talent disappeared. So, it was natural for them to assume Zephyr resentmented them.

Now, if he suddenly became talented again, would they see a vengeful threat or an asset?

Most likely, they would classify him as a threat.

The tower might choose the safe option of eliminating him rather than letting him grow. Thus, he felt like mediocrity was his shield and the lightning artifact the best cover.

For that, he fabricated the artifact that spewed lightning to mask what exactly he had done.
