Calling all Riddle Masters to solve the Riddle of the week!

Perhaps it’s raised above the castle,

Unseen by friend and foe alike.

Yet still it’s there apparent,

Warning of a pending strike.

 

In truth it might bide at your side

As you sleep the night away

In falsity though, it causes fear,

And leads but to dismay.

 

You know the drill post your guess in the comment section below, when the correct answer is posted I will confirm!
