well, she's originally mentioned in tBH, as one of the challengers picked up by the Edur fleet....

I'd say it's a fair asumption that they would have heard of Icarium, so that is entirely possible.
I'd be more inclined to think that once she was defeated by Karsa, she no longer had any reason to stay and fight when a more worthy challenger was present. That and she probably saw no reason to stay and possibly die when her own prowress has already been show up (Rhulad in no way threatens them so it's not a cause to die for).
