Notes:

Thanquol is the most Skaveny Skaven. No other Skaven character embodies what it means to be a Skaven as well as Thanquol does.

His most recent plan was to dig a tunnel from the capital Skavenblight and lead an invasion into the Realms of the Dead. However, he accidently had the tunnel come up under the sea, which drained the entire sea, causing an apocalyptic flood and the resulting undead hordes almost over-ran the Skaven capital city.
