[@Double Capybara], a few are planted in the Celestial Citadel, with metal pots to give them colours. This was the aforementioned gift to Ilunabar. Otherwise, I have not made any use of them yet.

[@Muttonhawk], I have another one. Slightly different feel, with less ill-at-ease feeling, but still plenty of mystery, and more instrumental, so might be useful for something.
