Of course, the main scenario is just the tip of the iceberg in terms of problems to deal with; players are also going to be tasked with heading back into the Great Gubal Library to retrieve untold tomes of powerful knowledge as well as venturing into Xelphatol to prevent another summoning of Garuda by the Ixal. There are also some preview images for the patch below, showing off the MSQ, the new Tomestone gear, housing additions, and the upcoming double-cross hotbar. So finishing off the Dragonsong War was not, in fact, the solution to all problems forever.
