Prophecy tablet (lighthouse)

Found after searching the bookcase in Silas's dream lighthouse during the Blood Runs Deep quest.

The inscription reads: When the tide is strongest, Good Intent will be needed once more.

This along with Prophecy tablet (hatchery) and Prophecy tablet (Glorious Memories) form a complete prophecy.

All prophecy tablets are destroyed at the end of Blood Runs Deep.

If you change your Fremennik name and then read the tablet, your character will notice that the name on the tablet has changed.
