How often do the different Races inter-mingle with each other?

[Dalvy]

That and there's plenty interracial love in the Rising Stone: Ocher Boulder is sleeping with a Hyur and that Hyur seems to be interested in Hoary Boulder ... perhaps an upcoming 3 some. Her sister seems to be against it though.

Then there's the miqo'te male who (apperantly) has eyes for the hyur cnj ... who happens to be stalked by a female miqo'te hiding herself in the dividers

It's just before you speak to F'hammin, you can see a female miqo'te starting wistfully at a male hyur conj from behind a screen.

Just before you first talk to Hildebrand's miqo'te friend, there is also a lalafell stating wistfully at her from across the alley...

There's some new NPC chatter outside the AST trainer that involves a hyur woman being forced into a marriage with an elezen male, and afterwards she stares wistfully at another (poor) elezen

It seems to me like hyur and miqo'te are the ones most willing to interact with and bang other races
