Song of the Earth
Lafayette is a city in the American state of Indiana, inside Tippecanoe County. In 1811 the county was the site of the defeat of Tecumseh’s forces, led by his brother, Tenskwatawa. This heralded the end of Tecumseh’s campaign against American forces.
A number of signs have directed the Avengers, especially Alex, to head to Tippecanoe. Gabrielle told him and Daniel they will find answers there, but they are not ready: there is a Marauder among them and they need to put their house in order.
As for what is in Tippecanoe, she alluded to only two things: one of the ten remaining Adepts of Time (a Traditionalist), not one of the Council of Nine; and one of three locations to which they may have gotten to her (the others being the Starlight Passage in Davenport, and the Cave of Tears in Hollow Earth, which they actually used).
