The End and the Beginning

From the introduction:

War rages between Cormyr and Netheril. While the battle for Suzail unfolds on the surface of Faerûn, a far more important struggle occurs in the realm of the unseen. The Netherese seek to create a new Shadow Weave and remake everything in Shar's image. The Order of Blue Fire wishes to ensure that the Spellplague's effects can never be undone. This is a fight not to determine the fate of the world, but to decide the very nature of reality. These are the last moments of this age, as the twin worlds of Abeir and Toril are sundered once more.

This is a two-round continuous-play Living Forgotten Realms Battle Interactive set throughout Faerûn and the planes for characters of the Paragon tier (levels 11-20).
