From Shaiya Wiki
Keolloseu is the capital of Erina, also known as map one. It is by no means the largest city, but one of the busiest. It provides for almost all the needs of characters below level twenty.
Almost any normal item below level twenty can be purchased in Keolloseu. The centre of the city has trade stalls, the liquid medicine merchant and accessories merchant can be found here. The blacksmith is found to the west of the city, and the protection and weapons merchants can be found to the east. One of the two guild masters on the lightside is located here, he stands in front of the fountain, which is located just above the stairs into Keolloseu if you are entering from the south.
The entrance to the 1-15 pvp area is found here (Delphinian Fortress), the gatekeeper is located in front of this portal. On the 'boardwalk' along the southern edge of Keolloseu there are also three portals, in order from east to west, portals to Apulune, Beika and Aelbaegeou.
