The Lingering Sentiment (Nightverse)

The Lingering Sentiment is the lost emotions and thoughts of a Keybearer by the name of Terra, who fell to Darkness. The Sentiment is among the most powerful entities in its home universe, and -- as the Sentiment -- has never been defeated, although Xion came rather close, and would be strong enough to defeat him now.

A brief list of quotations associated with the Lingering Sentiment.

Cut-Scenes
"There is nothing else to give you. All I have left are my regrets and my unending hatred for Xehanort. I failed them... Aqua... Ven... Master Eraqus... I am the embodiment of my regrets, and my hate. I am nothing more than the Lingering Sentiments of a fallen Keybearer." (Explaining the really, REALLY short version of his past)

Trivia

 * Even though the Sentiment never actually appears in The Nightverse, he is still categorized as such due to being a significant part of Xion's history, and their home universe isn't important enough to warrant its own article.
 * Even though he's not a member of Damage, Inc., he still uses their infobox because, through Xion, he could be considered very loosely affiliated with them.
