Spymaster Riddles 2

I have a message from Director Ring!  She has just completed her reconnaissance mission from Ephraim University, and has created some new riddles inspired by their latest poetry class!

A lantern with no battery or plug

Watch it at night to make you feel snug

Shines so bright

In case you forget a light

KYV DFFE

Quills and pillows, Tribal clans

Clothes of a bird and tools of a man

WVRKYVIJ

A horse that is running

with hooves that are thrumming

Armed with a sword

To prepare for war

LEZTFIE

King and Queen of Wonderland

Hearts and diamonds in your hand

TRIUJ

Hard as concrete, soft as foam

Carving valleys, rocks and stone.

Circles in the ground and air

Utmost importance everywhere

NRKVI
