Philosophers Tree
Face: "Deep lines mar the face of a wizened man, the pale wood looking all too fitting for his flowing beard. Yet the eyes almost seem to shine with the power of the mind behind them and the wisdom brought by such venerable age."
Location: "A tremendous hedge divides this place from the buzzing of the city and forms a wall to protect the place of quiet contemplation within. Many small alcoves can be found in the twisting passages, shielded from the sun by a roof of leaves, and invite the visitor to stay and rest or talk of matters of small or great import with his companions. At the very center of this maze stands a tall Weirwood tree on a small outcropping of rock with small pools of clear water gathering in between stone and roots. Around this tree stand a circle of moss covered, rough hewn stone tribunes, allowing many to gather beneath its branches to find wisdom and share it with others."
Effects:
CL 20 Hallow Effect
Secondary Effect 1: Wisdom of the Ages - By imbibing the water gathering at the tree, a person can try to gleam some knowledge of ages past from the Old Gods and commune with the greatest minds among them. The person must meditate beneath its branches for an hour to gain a bonus to all Knowledge checks and to all Craft of Profession checks used to teach, learn, invent or refine theories and ways of working. This also allows the subject to make these skill-checks untrained. The height bonus can be freely chosen, up to a maximum of +20, but the person must pass a Will-Save with a DC equal to the desired bonus. If the subject fails this check, he does not gain the bonus and becomes Nauseated for an hour, as the insights gleamed from the Old Gods overwhelm him. Every hour after receiving this bonus, the person must pass another Will-Save of the same DC or the effect ends and leaves him Fatigued. The effect also ends if the person leaves the maze, but he must not remain in the inner sanctum.
Secondary Effect 2: Tongues - All persons within the inner sanctum can talk with each other as if speaking the same language and perfectly understanding each other.
Secondary Effect 3: Discern Lies - Any person who tries to speak an intentional lie in the inner sanctum must pass a DC 25 Will-Save or all other persons in attendance know immediately that they were lied to.
I combined Anamensis and Tears to Wine into a single effect, while giving it more flavor and some clear requirements / restrictions. Has the added benefit of making a few nice pools for the Lotus Leshy, who will probably love this place.
The Tongues is mostly for the benefit of foreign scholars, who I think will gladly come for this tree and Discern Lies is to make sure that nobody tries to run a con by claiming great insights that he doesn't have.
They are also not that grand effects, to balance out the combined first effect being able to pack quite a punch for those daring the higher bonuses.
I also hope that this tree has a good effect on the Old Gods themselves, since it gives them some interactions with mortals that don't involve blood sacrifice and let them glimpse into the hearts of minds of the people coming to the tree.
The main goal of this tree is science and establishing SD as a center of learning.
Incidentally, it would be a great place for Viserys, Lya and the Bulabar to discuss piping and steam.
