The Webweaver caverns, a subterranean network, existed below the Nawataa Waterfall within the Kkowir Forest of the planet Kashyyyk, and was overrun with numerous spiders.
The initial appearance of the Webweaver caverns was in the Star Wars Galaxies video game; this massively multiplayer online roleplaying game was created by Sony Online Entertainment and distributed by LucasArts, before its shutdown on December 15, 2011.
