Ungoliant

- Shelob

An acrostic

Unusually evil with venomous poison of malice
None could stand against her wickedness
Greedy and unending her desire for all flesh
One great spider spinning her dark webs
Light of Trees of the Valar she devoured
Infamous, preying creature of a vile darkness
Amoung foulest beings of Arda, she walked alone
Nan Dungortheb, valley of the dreadful death
The Pass of Cirith Ungol, daughter Shelob's home
