So, apparently the capital of the Skaven in the new universe is "Blight City", possibly a former Dwarven/Human city. The clans are basically unchanged, bar most (but not all) of the former historical characters. The only new additions to the lore/rules are a few excuses to sell new terrain/spell effects. What was the point of the whole End Times again? They retained so much that the destruction of the world feels very halfhearted, yet removed so much that it will take many more years for it to feel remotely less empty than it does now. At this stage, it appears they could have achieved the same by just advancing the storyline a few centuries. The only truly major shift would have been the introduction of Sigmarines, but any half-baked attempt to make them fit in would likely have been preferable to blowing up the entire world and then introducing them.
