Garden of the Flowers of Resilience

The Garden of the Flowers of Resilience is a field in the 4th layer that is filled with Eternal Fortunes. It is said by numerous Delvers that the garden is one of the most beautiful places that can be found deep in the Abyss.

Most of the Delvers, who come across it, rest here for a while just to look at the beautiful scenery of the garden. It was one of Lyza's favored places in the Abyss.

The garden was classified as especially dangerous, because of the migration of the Amaranthine-Deceptor, due to them taking advantage of the cover the flora provides and had to be destroyed.

History
Ozen found the Everlasting Pickaxe marking a grave in the garden, though it was later revealed that the grave was empty. The Everlasting Pickaxe was given to Riko, as it had been her mother's signature weapon.

Later, after leaving Nanachi's Hideout, Riko, Reg and Nanachi are travelling through the garden, on the 4th layer, when they spot one of Bondrewd's Umbra Hands. When Reg goes to go inspect what the Umbra Hand is doing, he is given back the Everlasting Pickaxe, which had been lost ever since Orb Piercer had attacked Reg and Riko. As Nanachi and Riko observe the situation, Riko notices a bug pretending to be one of the Eternal Fortunes. Reg finds out from the Umbra Hand that the entire garden is infested with deadly Amaranthine-Deceptors.

Amaranthine-Deceptors usually reside in the 6th layer, but for unknown reasons have begun to infest the upper layers as well. The Umbra Hand infroms Reg the Amaranthine-Deceptors have already increased their population too much in the garden and proceedes to burn the whole garden, so that the Amaranthine-Deceptors will not spread any further.
