From-Deepest-Fathoms, the Argonian involved in the quest Unfathomable Depths, has her name unhyphenated as "From Deepest Fathoms" in an objective from Unfathomable Depths, and her name is also weirdly hyphenated as "From-Deepest Fathoms" in the journal entry for stage 900 of the quest.
Thirdly, unlike usual hyphenated Argonian names that get their last word to be the short name in the subtitles, (Deep-In-His-Cups becomes Cups, and in the same quest, Watches-The-Roots becomes Roots), yet it seems that her short name has a typo, seeing as it is "Fathom" instead of "Fathoms".
