I'm going to try to post updated maps of Sidhe and Banagher's travels. I know that in the ROC, there's probably some debate about how the Redwall world correlates to the real world, but for this story, real geography is taken literally. Maybe I'm just not imaginative enough. Maybe I'm just interested in sending Sidhe and Banagher to places I wish I could go. Probably a bit of both...

[Map 1 - Chapters 1-4]

Here you can follow the route of the slave ship [with Banagher already on it], and you can see where Sidhe was picked up, in Madagascar. The ship went down just south of India, where the duo landed.
