The Ravenblack Grimoire

The Archisium is a notorious weed, (in)famous for attempting to remove a garden from the City without RavenBlack's permission, but still sending out sub-weeds to infest other areas. It started off as a white flower, but a couple of times in history it has developed a rosy pink shine to its leaves.

Quite possibly the oldest weed in the City, this species has all the subtlety of a Redwood tree falling on a house. Studies have shown that if you leave a floret of Archisium in a bowl of water without other seeds, it gets delusions of grandeur and attempts to take over the City. It has quite a noxious smell, especially during this period, and its seeds contain a highly toxic substance.

It is not all bad however - scientists in the Capadocian Castle have found that the Archisium makes a great tool for curing stuff. Quite what this stuff is has yet to be determined, but all the eminent people fully agree that the Archisium is a big tool.

These days the Archisium can be found in the gardens around the Capadocian Castle, being carefully cultivated by the teachers in their Dojo.
