GIANT MUSHROOM TOWER
The cavern around Yggmorgus is huge. and the giant
mushroom nearly fills it from floor to ceiling.You have no clear reference to judge the towering
mushroom's size at this distance. Thousands of smaller
fungi cling to the main stalk, which itself splits into
several lesser stalks, each long enough with a cap big
enough to be the top of a great tower. The cavern floor
surrounding the stalk is covered by a carpet offungi.
An eerie luminescence pours through slitted windows
carved into the trunk, with the same cacophony of atonal
music heard earlier echoing within. A stench of rot
and decay wraps around you, seemmgly threatening to
penetrate your flesh and pervade your soul.Yestabrod's Garden of Welcome is a pale reflection of
the true horrors surrounding Yggmorgus. A 20-foot-
high crescent-shaped ledge hugs the cavern wall and
gradually slopes down to the lower basin. The ledge
IS covered with a carpet of moss and fungi, scores of
\'ariously sized lumps, and pockmarks where pools of
,·ile fluids suppurate and ooze, some drying out and
scabbing over. The entire ledge is difficult terrain.
Characters venturing this close to Yggmorgus must
succeed on a DC 11 Wisdom saving throw or gain one
level of madness (see '·Madness'' in chapter 2).
Characters can discern the shapes of writhing
creatures i nside each lump. Most of these arc
humanoids, though a few of the lumps arc occupied by
what appear to be gricks, nothics. and giant spiders.
This is the Great Garden of Rot, nourished both by
•he creatures subsumed within it and the faerzress
pervading this cavern.
As if on cue. one of the lumps closest to the
rharacters bubbles up and bursts. A dense cloud of
~pores and dark, reeking fluid explodes outward. even
a~ the characters hear a piercing scream of agony and
·error. [nsidc the pockmark left behind by the burst
is one of Xinaya's drow scouts or at least what's
left of him. Other than a face, long white hair. and
a breastplate, it is impossible to distinguish where
•he drow ends. and the rot and fungi consuming him
begins. The drow feebly thrashes. his screams rising
ever higher in pitch, until he locks eyes with one of
the characters and abruptly stops screaming. A brief
moment of lucidity replaces his terror, even as his eyes
roll back into his head in some kind of bizarre euphoria
as he goes limp and slowly sinks back down into the
'ungal muck. Characters witnessing this must succeed
on a DC 13 Wisdom saving throw or gain one level
fmadness.
Throughout the entire cavern. loud moans and cries
of agony answer the drow's screams in a terrifying
and deafening chorus, drowning out all other sounds
until eventually winding down into a low susurration
lf groans and burbles. The entire stalk of the giant
Mushroom seems to shudder. almost as if in delight.
