Mummy Wrappings
-
Rente Willer would search both Arcane and Public libraries for information regarding Mummy Wrapping. Specifically he would strive to find out whether they tend to have any magical properties, are they used for enchantments, crafting, and he would also seek to find stories relating to Mummy Wrappings holding any special magical powers.
This would mainly concern Ancient and Older Mummies, rather than new ones.

They appear to be used to wrap mummies. Beyond that, there's plenty of conjecture that they're enchanted to preserve undead flesh or may even absorb negative energies. Nothing certain though.
