A pleiades is another interesting poem I found. Based on the constellation the poem has seven lines (seven sisters) and six syllables in each line. Each line starts with the beginning letter of the title.

Fire (Pleiades)

Free energy of light.

Fierce inferno of heat.

Forge warriors' weapons.

Fighter of elements.

Finish your enemy.

Fuel their destiny.

Flames of red tongues reach out.
