Karim

Karim was an adventurer in ancient Persia who, in accordance with the demands of his lover, went off to an ancient temple hidden in the desert to fetch a mysterious artifact in exchange for her hand in marriage. When Karim arrives at the temple, he discovers it to be infested with zombies and other monsters. Armed with his tulwar sword and other weapons, he dispatches these creatures and makes his way to the center of the temple, where he finds the artifact, only for the ghost of his lover, who was murdered while Karim was away, and sacrificed himself, staying in ghostly form for 500 years until another found their way into the temple.

Tulwar
The tulwar in Eternal Darkness is anachronistically placed, actual swords of this style not appearing until the 1300s. Regardless, the tulwar is a curved Indian sword with a curved blade. Karim's tulwar appears to be about two feet in length.

Ram Dao
Couldn't find a free to use image, so look here The Ram Dao is a massive Nepalese sacrificial sword, with a large heavy blade designed to decapitate an animal in one blow. The sword is heavy, looking similar to a giant machete, with an eye carved near the point. It is not explained exactly why this Nepalese sword was lying around in a Persian temple...

Chakrams
The Chakram is an Indian throwing weapon consisting of a bladed metal ring. The chakram could be thrown either held between the fingers like a frisbee, or by spinning the chakram around the index finger. Chakrams could also be used as melee weapons, though Karim never does this in game.

Torch
Karim used a flaming torch mostly for illumination, however, he found it could also be useful for setting fire to the dried out flesh of some zombies.
