The Arcanium is a large, circular area, approximately 100 metres wide. Is one of the most heavily guarded areas of Ivykeep, besides the Ivykeep itself. The Arcanium has the strongest known Quinta concentration in the kingdom, and is said to have been an original Point of Genesis.

The Arcanium is used almost exclusively by the Arch-Mage, likely due to its high concentration of both Quinta and Blackstool. No civilians have ever entered the ring.

The Arcanium, while not known to have any internal defenses itself, is surrounded by the Sunshine Pastures Exclusion Zone which acts as a buffer.
