Zephyr the Zafara was attempting to read a letter she just received. However, after getting lost in a rainstorm, the letter became wet, blurring many of the letters.
After going over the letter over and over again, Zephyr was finally able to figure out what it said. However, she still needed help with the last word.
The crumpled and ruined letter reads as follows:
YwlldfndyrslfgnstflckfnrgdKs.
What is the last word?
Please answer with only the word and nothing else.
