The Force Glyph

I followed the path to an uncharted ground
Quite eager to see what was there to be found

And once I ascended the incline ahead
I made my escape from the realm of the dead

This space was quite small, with no evident risks
But only a statue and three obelisks

I toppled them all; nothing happened at first
However, I felt a precipitous burst

The statue above slowly opened its eyes
Revealing an item I don't recognize

Upon its descent, the ground slowly pulsated
And then I approached once the tremors abated

The relic divided the ground from my toes
And then it encircled me as I arose

I garnered its power; the spell was complete
And once this was done, I returned to my feet

The Voice then informed me of what I'd achieved
And how I could harness the glyph I'd received

Its power elicits unyielding surges
Repelling all enemies as it emerges

However, I must not depend on its gain
Each time that I use it, my power would wane

There's nothing left here and no reason to tarry
I now must proceed to the Clans' sanctuary
