Light

Like a beacon

Explanation

Beacons, often in the form of lighthouses, were built on coasts to give ships a point of reference where land was, so that they could find where they were going, and to know where they should avoid during a storm. In the comic, Megan fills this role for Cueball: she is his beacon to know where he can be safe. This also has a romantic notion, as Megan is lighting up the world for Cueball to find her.
