Seswenna Hall was a large civic center in Eriadu City. It was built to look similar to the Senate Building on Coruscant. In 33 BBY, the hall was the location of the disastrous Eriadu Trade Summit. The summit was successfully infiltrated by members of the Nebula Front under the direction of Havac. Captain Cohl and his partner Boiny foiled the plot to kill Supreme Chancellor Valorum with the help of Qui-Gon Jinn.
