The party has arrived at Poor-vh Shi-khar, otherwise known as Cliffside Spire. They were asked to come here by Vanus, to seek his son who had not responded about his mission in a while.
The party find Natakas, Vanus's son, in a body bag ready to be offered in a summoning ritual to some purpose by the Tsaesci. Aside from Tsaesci, they also find Higashi humans who are members of the Yakuza. They dispel a teleportation circle on the roof of the Tower, and defeat both Yakuza and Tsaesci foes in the tower.
