Great Oak

The Great Oak was a magical tree that existed in Kuldahar. It was the reason that Kuldahar was in a state of eternal summer and had no trace of snow, unlike the surrounding areas. When linked with the Heartstone Gem, it could radiate a large circle of warmth.

History
Thousands of years ago, the great oak was once a divine seed. On the plateau near the tree, belonged a yuan-ti outpost. The yuan-ti took interest in the spot which the Great Oak grew, as it was the gateway to a distant land.

When Kuldahar was invaded in the early 14th century, the tree was repeatedly hacked by the brutal yuan-ti. They managed destroy several of the Great Oak's roots. The archdruid, Iselore, stayed to protect it.
