Dilapidated Arboretum

The Dilapidated Arboretum is a second level biome that was introduced with the Bad Seed DLC.

Dappled light, soothing fountains and a fresh air brought the royals, aristocratic and various hangers-on to the gardens and serres of the arboretum to escape the hustle and bustle of the castle to have some moments of peace and relaxation. However, the fragrance of their perfumes had, unbeknownst to them, disturbed the local flora and fauna. Now the arboretum, a shadow of its former glory, attracted a different kind of visitor, who enjoyed the earthy smells of compost, spores and decay very, very much.

Access and exit
The Arboretum can be accessed from the Prisoners' Quarters via a Teleportation rune after having first accessed the area with the Dilapidated Arboretum Key.

There are three exits out of the Arboretum, which consist of the Prison Depths (requiring a Spider rune), the Morass of the Banished, and the Ramparts.

Scrolls
The Dilapidated Arboretum contains 3 scrolls, including 1 Power Scrolls, and 2 Dual-Stat Scrolls, which cannot spawn in areas requiring the use of runes to access. On (1+ BSC) there is a bonus Power scroll. When 3 Boss Stem Cells are active, this biome has 1 guaranteed Scroll Fragment, and when 4/5 Boss Stem Cells are active, this biome has 2 guaranteed Scroll Fragments.

Botanical beaker room
The room depicted in the following picture contains three items that can be examined:

Order
When examined, the Beheaded reads the following text written by an unknown person, presumably some sort of guard:

"Apparently seeing the dead rise wasn't enough.

"Today it's the plants that are up and raising hell."

"The King's new best friend has ordered one of them captured... Alive..."

"...I'd like to see that!"

Botanical beaker
When examined, the Beheaded says this in regard to the display before it:

"How did they get the skeleton in the bottle?"

Books
When examined, the Beheaded observes that:

"“Man vs Wild” and other botanical treatises are spread out on the ground."

"I wonder what's in this flask..."

Trunk
Upon examination, the Beheaded says the following:

"It seems like these infected ones were trapped in the trunk..."

"Makes you wonder who was the sick one in this story..."

Skull
Upon examination the Beheaded makes the following observations:

"The skull of a giant crow mixed in with various bits of mushed and mashed organs, entrails and local roots..."

"...connected to the bark of an old red giant tree."

"The perfect evil wizard starter kit..."

Luxurious chaise longue
Upon examination the Beheaded exclaims the following:

"Varnished wood... satin pillows..."

"A bunch of leather bound books..."

"I wonder which noble had their personal garden here."

Chaise longue
Upon examination the Beheaded exclaims the following:

"Gloves, a pitchfork... Maybe a courtier tried their hand at gardening?"

"No, you wouldn't find one that would sit on such a shabby piece of furniture."

"Or wear this outfit."

"It seems the gardener had his entrances into the palace too."
