Devs, Stick to your guns or remove Viera all together.

When the game and the book clash, I go with the game.

The game could be changed if it was wrong, and the book is written with an out in the first few pages, where it describes itself as a collection of 'histories, legends, fables and folktales.'

The reference to adventurers seems to exist in english localization only, from what I see.
Even then the lorebook does mention that we gather companions sometimes, increasingly so in volume 2 (SB), regardless the playerbase at large does not have any bearing on the population which was my original point. It's still a handful of echo pals, not an entire colony of catboys in Limsa.
