Locations in Shaiya:
Lupers is on the west side of the bridge that is near the tower at which you got the quest. Don't ever say "Lupers" in trade chat. Honestly, there are so many people that ask about him, that it's tragic.
Dolama and Delano are east of Keolloseu. One is on the island, while the other is on the beach near some rocks.
Kaznil can be soloed at 18, and sometimes even at 17 level(Shaiya powerleveling). He is straigth south from Keolloseu, right in front of the mountain. He looks like a big Ogre Chief.
Cloron Goblins are west of Cloron, in between two rivers. Isprit is east of Cloron on the other hand.
Dread Quests (Light):
If you are HM and want to get dread gloves, you need to finish all quests given by Creath Question. Do not cancel them. To do so, you may also finish one quest given by a lady under a tree, near the crossroad south of Fedion. There are four dread quests (respectively, 25, 26, 27 and 28 level).
First one, for gloves, is obtained by getting item named Poemas Mandolin from Juliah Dillun. You must finished Creath's Question quests to activate the quest. Second items(shaiya gold) quest, for boots, is obtained from Sealakel Fighters, and is named Monkey Skull. For pants, third quest, you must get Empty Trunk from Orc Robbers. Fourth quest is initiated from item called Lens Bow, dropped by Priest Dempnun.
