Sentinel of the Seas

Sentinel, steadfast on the shore, Entrenched in solid rock. Neptune, enraged, rumbles and roils Throws bolts to stun and shock. Iredescent, the greenish glow, Nodes of Elmo's fire. Endures, unshaken the Keeper Laugh at Nature's mad ire. Lost on the pitch-black, tossing sea Eager eyes scan the dark. Nothing to warn them of danger If not the distant spark. Thus saves the Sentinel the ship. No mariner's at ease Except when succor he has seen - Sentinel of the Seas!
