Tidal Forest/Water Hazard
The Jesk family inn.
The Ogre charged at the small goblin and ran out after it only to find the dried crust cracking under it’s feet, plunging it into the ooze. It roared with rage, but the more it tried to escape, the deeper it sank. "Welcome to my homeland," said the gopblin with an grin on it’s face. "You were a fool to chase me in here, and now I’ve got you right where I want you…"
"After being to the Bramblefens, blackberry thorns just seem kinda cute!"
A slightly atypical stinking swamp festering with goblins
The Sorcery Springs Geyser Basin is a place of bubbling magical water, as every individual spring or pool has it’s own magical power. It is a place of great wonder and for the careless, great danger too.
The Swollen Shadow’s magic is such, that anyone transported to its demi-plane, will always first arrive in the somber and hazy Umbral Fens, which surround the City of Shadow. After some searching one may find the Brittle Road, which leads through the shadow-choked swamps, to the City proper.
A wasteland, a vast expanse of ogre infested, nightshade choked swamp…
You find a patch of edible funghi. They taste well and all, no ill effects. UNLESS you consume some beverage, even 3 (three) days after eating it. Then you become really sick with pains, vomiting, all the fancy stuff. As a gift or good meal, it could be a cruel joke or to make sure the heroes spend their time focused on the mission. And the fine soup you had in the inn yesterday could have some in.
(Inspired through a real-world fungus. Was really used to cure alcoholism.)
