Spirit Soaring

Location
Cadderly Bonaduce built the temple to Deneir high in the Snowflake Mountains, it cost him a lot as the magics used drained him and aged him remarkably, but once it was finished, though he thought he might die in doing so, Deneir reversed the aging process so that he would go back to his natural age over time. The closest city to the temple is that of Carradoon, with a large lake and a fair sized fishing fleet.

Inhabitants
Cadderly Bonaduce, the priest of the temple, Lady Danica Bonaduce, the wife of Cadderly, Pikel Bouldershoulder, a dwarf druid and gardener at the temple and Ivan Bouldershoulder, Pikel's brother.

The Temple
It is described as a cathedral in Passage to Dawn though the dwarf can't actually pronounce it say he calls it a church instead.

It has a special room for calling creatures from the Abyss, as Cadderly does with Drizzt watching. Unfortunately, in this book, it actually frees Errtu, allowing him to come back to Faerun because of Drizzt's prescence and knowing what Cadderly is about to do.
