Giant tree that pervades all of Bogroot Swamp. Called “the old snake-haired toad” by the locals. The prison of the Demon Elsifor, bound to it by the Starlit Door.

You stand at the foot of the giant mangrove, which towers silently over you. Its many leaves rustle in a wind high above while you remain stuck in the oppressive swamp heat below. The trunk of the mangrove is as wide as a small village, but someone has tied a purple silk ribbon inscribed with silver runes around it. - Bogroot Demon (RPA-ADV6)

You first meet the Demon Elsifor at the base of the tree, after surveying the area or inspecting the ribbon wrapped around it;

You recall the meaning of the runes and decipher them. This is an ancient holding spell that binds one physical form to another, and it is marked with the Eye of the Starlit Door. - Bogroot Demon (RPA-ADV6)

Upon delivering all of the ingredients to Mugbok for a purification potion, you return and pour it on the roots, freeing Elsifor and the Frogkin of Sandhill Village of his misbehaviour.

Once Elsifor has been relieved, the area grows much more peaceful, returning to its tranquil ways;

The base of the mangrove is strangely quiet and serene. Sounds of swamplife fill the air around you. A cool breeze wafts over you, carrying the sweet scent of distant cooking fires. - Bogroot Demon (RPA-ADV6)

Arriving at the base of the tree, you can document it on your map in one of two ways:

• Draw the tree romantically as a snake-haired toad and preserve the oral tradition.
• Draw the tree factually and maintain understandability for any reader to use.
