In norse mythology the Yggrasil tree is the world-tree with roots going to all domains, to the dwarves, humans, trolls, alfs, et.c.. Yggrasil routes its traffic over mostly the internets, but can also tunnel through Tor, I2P (i2pd) and LokiNet, so it's nigh impossible to trace those users that read the manual and knows what they are doing (i.e. peer only via I2P or Tor).
