A silent vestige sits among the vine covered ruins in a forest that has overgrown who once lived here. No more towers rise among the skeletal remains of a seeming once vast city.

“Wait, is that the same Damn tree we’ve been seeing all day?”, Ured the strong demanded.  “No… Yes, yes it is.” stammered Fenstill the mage. 
“Well, I’m sorry, but I’ll have to kill you now…” said Ured, drawing his sword.  “I understand,” said the mage, wondering why he got into the magic business anyway…

With apologies to Monty Python…

While one cannot deny the beauty of the Giant Foxglove, it is tempered by the knowlage that the beauty hides its deadly nature.

An extremely exotic tree that is unlike any other. It is used world wide in the finest palaces and establisments…

This glowing fungus has been known both to save lives, and to ruin them as well.

Demontrumpets, as illuded to by the name, are not normal plants, but are plants who hold their origin in the Abyss. Perhaps brought by summoned demons, perhaps created by a dark god for some purpose, perhaps simple plants mutated by an artifact of great evil.

Brendan stared at the creature in the pale moonlight, transfixed by the silvery petals that glistened beneath that perfect purity.
