Here's a link to every single graphic from Daggerfall. It includes TONS of monsters, weapons, textures, and other objects. It has 41 different monsters, a lot of different medieval weapons (sword, dagger, mace, flail, warhammer, axe, bow), most with several different attack animations, as well as magical attacks. It has graphics and flora for everything from swampland to desert to rainforest to mountains. It has textures for (medieval) cities, graveyards, dungeons, taverns, wizard's towers, etc. It even has animated skies for sun/moon-rise/set from both East and West! The file includes all the menu and paperdoll inventory graphics as well.

Here are some of the enemies and weapons. The weapons would be ideal for any sort of medieval mod.
