In the middle of a vast but secret forest stands the Arch Oak - a majestic tree that was a young tree when the world was young too. It is even said that the gods made the first humans and animals from wood.

Druidic beings from far and wide gather around its roots to bathe in its glory. Archdruids place saints and erect monoliths with runes, while bards tell stories to gain a larger following. Ovates read the omens to get a glimpse of what is to come, while sacrificers use violence to defend the beliefs of their Order.

Oak puts you in the role of the leader of one of four different druid orders, as you attempt to determine that your order deserves to be chosen by the spirit of the Arch-Oak and learn its secrets. You start small and insignificant, but if you choose your actions wisely and use your druids efficiently, you will find yourself growing in power and stature.

You will gain the friendship and help of aliens such as the mischievous brownie, the terrible merrow and the magical fairies. You will learn powerful spells from the wild and discover powerful artifacts. You might even risk upsetting the natural balance by creating new sacred places in the forest to house your growing number of druids.

Can you prove your worth to the Arch-Oak? Can you unravel the secrets of the ancients?
