Looking for Druid ruleset?

[discok3]

Gents and Gentesses,
I was lucky enough to play a demo game called Druid at Salute a few years back.It was run by Wargames Illustrated and was for 4(ish) players.Each Druid was accompanied by a small warband of Dark Age type soldiers and he had to collect items from the earth to allow spells to be cast
I really enjoyed it and followed up by enquiring as to whether WI would be releasing it as a game but alas they decided not to.
SO my question is does anyone have any rule sets that would be suited to emulating something similar?
I really don’t want to have to do lots of adapting of rules so if there’s a set out there could you avail me of your knowledge?
Thanks in advance
Kev
