I’ve been working, off and on (more off than on) on a couple of 15mm fantasy armies for some time now. I got them out and started working on them again after being inspired by the figures in this gallery.
Glorantha is a classic fantasy world created by Greg Stafford that is featured in role-playing games like RuneQuest and HeroQuest.
Greg Privat has created a website with pictures of wargames miniatures painted to represent various armies from the Gloranthan setting. Many of the models are conversions from ancients ranges, particularly Foundry and Gripping Beast; others are rare and obscure models, conversions and scratchbuilds.
The City of Solis website has some good looking, hand drawn banners that you can cut out and use with your Warhammer, Chronopia, or other fantasy armies.
The Blue Mule website has a pictorial record of some of the early figures in fantasy gaming. I’m showing my age, but I remember a lot of these figures from when I was in high school and college.
Games Workshop’s Lord of the Rings battlegame boxed sets come with some bits of terrain to get you started. This page has some paper buildings for Rohan and Gondor to keep you moving along.
