It is possible that the colony was once known by a different name - but as it is located outside of the known galaxy, that seems incredibly unlikely.

The war in question is a conflict between Verdana and its sister world, Antiqua. Unfortunately, there is only a limited amount of information available on it - the passage of several centuries, and the terrestrial conflict that sprang from the aftermath of that war has served to eradicate much of the historical record, at least locally. As for the fog, I do not believe the locals have studied it beyond learning how to avoid it or control its effects. If anyone who awoke on the ship did so the last time it occurred, they did not think to leave a record of their findings.
