Sealville is one of the few cities in Trans-Antarctica that is capitals of the seal "nation". Sealville is the only city that is populated fully by harp seals, with the exception of several terns and seal-loving penguins.. Sealville is directly west of Skuavo. It was founded in 2006 by several peace-loving harp seals that feel the seal colony should not be extinguished by penguin civilization. It is the second largest city in Trans-Antarctica, behind Pengu Town and after Newton Town.
