I heard a story about a temple of Isis, who was worshipped as a god in ancient Egypt. It is Located somewhere midstream on the Nile. Maybe some treasure can be found inside. Althought I don't know any information more specific than that. You can probably learn something if you go to Cairo, which is a town on the Nile River basin.
Step 1 - Rampant tomb robbing:
[Cairo] - talk to Customer (blue clothes)
The Temple of Isis? You a grave robber, too? Lots of that going round these days.Was asked about the same thing by some other adventurer just before.
Rumour of some treasure is spreading fast. The Temple of Isis is just a bit up river from here.
Huh? you well-built young man, you have something to say?
Step 2 - Fate of the tomb robber:
[Cairo] - talk to Customer (black clothes)
Lost of bandits targeting the grave robber bunch, there are.
Just before one the grave robbers i guided to the Temple of Isis was set upon by some bandits on the way back.
Was in the middle river area, up river from here. I was spared somehow, and I saw them hiding an idol in the table rock area, south of the dock.
Final Step - Treasure of the temple of Isis:
[Central Nile] - near southwestern Table Boulder
Seems that the idol taken from the Temple of Isis was hidden in the vicinity of the table rock located south of the dock in the middle river reaches of the Nile.
Whilst there is an air of danger about that area, slip in somehow and check it out.
