The rashiliyia corpse is a quest item used in the Shilo Village quest. It is obtained near the end of the quest by defeating the three forms of Nazastarool in the tomb of Rashiliyia. The corpse must then be placed upon the dolmen within the Tomb of Bervirius, located underneath Cairn Isle, to complete the quest.
The item was renamed from "Rashiliya[sic] corpse" to "Rashiliyia corpse".
Trivia
If you already have the corpse in your inventory, such as from picking it up via the right-click "Search" option on the tomb dolmen, then attempting to pick up the item itself from on top of the dolmen will yield the message The object must have been a trick of the light...
