The tide of TERA news keeps on flowing in with the release of the first eBook series exploring the lore behind the MMO.

The Amaranthine Heart released this week, and follows the story of an underdog within the Valkyon Federation.

The eBook is available on for 99 cents.

TERA is due to launch May 3, however it has been available in South Korea since January 2011 and has spent the last year being localised for North America and Europe.

Recently we spoke to the producer for TERA Europe, Stephan Krippendorf, about the combat slant of the MMO and how that prevents it from becoming an MMO clone like many other titles.
