Lotus Nexus

An old warehouse beneath Plaza of the Seven, the The Cult of the Wandering Shard planted here the Lotus Nexus and let it grow. By June 23, when the Fateless Eight traced it down here, it had grown enough to start manifesting a "domain" / lair, themed around roots and ice. The entire place was run over by roots and Grave Lotus' buds and flowers.

Once the Lotus Nexus was slain, its core rotted, revealing the Elemental Essence Shard (Ice) and a frozen, bejeweled Grave Lotus flower.
